Here we go again, the Update Keychain Password Function is broken again in 10.15.1.
The AD “Update Keychain Bug” was fixed in 10.15.0, only to be Broken again in 10.15.1.
UPDATE: 03/26/20 – The bug is fixed after installing the Catalina 10.15.4 Combo Update!
UPDATE: 02/03/20 – This bug is still not fixed in 10.15.3! Please contact Apple about this if you haven’t already.
When the issue was first reported to me, I really didn’t believe the bug could be back right after it was fixed. You have to understand my frustration here, I first reported this bug back in 10.14.4!!!
I was disappointed that Apple didn’t fix this bug before the final release of Mojave. Near the end of Mojave, Apple did confirm the issue was fixed in a Beta Build of 10.15.
For Mojave users the fix for the issue would be
Upgrade to macOS Catalina
The bug is back.
During the 10.15 Beta period, I confirmed the bug was fixed in and figured that would be the end of it.
Yesterday, I confirmed the bug is back in 10.15.1.
The Bug is Exactly the same as the 10.14.4 bug.
The 10.15.1 Update Keychain Password bug is the same exact problem as the 10.14.4 issue.
If you change your Active Directory Password off the Mac, you will see the Update Keychain Password Dialog. If you click the 2nd button to UPDATE your login keychain password, the dialog box disappears and a new keychain is created for you. The old Login Keychain is still there but is renamed!
This is what you SHOULD see happen. Once you click the Update Keychain Password button a password box shows up. From here you need to type in your OLD keychain password. Once you do this, your Login Keychain Password is synced up and you are good to go.
Workaround
The good news is, you can remove the “New” keychain and rename your previous login keychain so you can access it again. You can follow the same instructions listed in my 10.14.4 article.
I will submit an Enterprise Support ticket tomorrow morning. If you use Mobile Accounts, I would ask that you do the same to build an impact statement. Please reach out to your SE or if you are a regular user support.apple.com/

I’d like to give special thanks toMr. Macintosh reader Cesar who first reported this issue.

The much-awaited MacBook Pro (16-inch, 2019) was just released this morning! You can’t get it just yet, but very soon. (November 15th)
To accompany the new 16″ MacBook Pro, we have a forked Build Version of macOS Catalina 10.15.1 (19B2106) Installer.app. We also have a macOS Catalina 10.15.1 supplemental update.
The macOS Catalina 10.15.1 supplemental update improves the stability and reliability of displays and peripherals with MacBook Pro (16-inch, 2019).
Catalina 10.15.1 supplemental update notes
Supplemental Update ? (UPDATE)
I am not sure what’s going on with this update. You would think that all the new 16″ MacBook Pro’s would just ship with (19B2106). If not then what is the Supplemental update for ?
I am downloading the Supplemental Update now so I can investigate.
UPDATE!
I found the MacBook Pro (16-inch, 2019) shipping 10.15.1 Build Version.
10.15.1 (19B2093)
This means that as soon as you receive the new 16″ MacBook Pro, the 10.15.1 Supplemental Update (19B2106) will show as available.
What’s New in macOS Catalina 10.15.1 Update (19B88)?
macOS Catalina 10.15.1 Update (19B88) is now Available.
10.15.1 is Catalina’s first Update was just released and it’s now available for download. Let’s take a quick look at the Catalina 10.15.1 Update (19B88) and see what’s new.
First thing to note is the SIZE of the update! The Point Update clocks in at 4.49gb!!! That’s over 50% the size of the main installer app! (The full installer is 8.63gb).
macOS Catalina 10.15.1 is the largest update ever?
This update may be the largest OS point release ever released by Apple.
Speaking of size, hopefully your Mac has enough space!
When you have an update that is almost 5gb in size, you also have to take in to account how much extra free space you will need. For this update you may need up to 20gb of free space to even install the update.
For the 10.15.1 Update, you may need up to 20Gb of free space to even start the installer. HT goes to @nstrauss for the screenshot.
If you have the update set in a Jamf Pro Policy you may get en error in the policy log like this.
Update Failed due to not enough free space. HT to @funkaround for the screenshot.
The full installer app was also updated and is 8.6GB in size.

How to Manage Catalina’s New Application Notifications with a Profile
This article will show you how to Manage Catalina’s New Application Notification Preferences with a Config Profile.
Now that Catalina is live, MacAdmins have many questions. The top 3 questions I have seen so far are;
1. How do I block macOS Catalina from my users?
2. How do I Manage macOS Catalina Application Notifications?
3. What are the new Screen Recording and Input Monitoring or Keystroke Receiving TCC Settings? (more on that in a new article.)
Catalina Application Notifications Index
1. Should I manage Application Notifications?
2. How do I reset or clear out previous Notification Settings?
3. How can I test the Notifications Profile?
4. Find Previous Bundle ID or App Domains from past Prompts
5. Manage Notifications with a Profile.
6. Notifications Profile with Profile Creator.
7. Notifications Profile with Manage App Notifications.bash
8. Credits
1. Should I manage Application Notifications?
This is a question you should ask yourself. Keep in mind, once you mange a profile setting it can not be changed by the user. Managing certain application notifications from Jamf Self Service is one example. You WANT the user to be able to see the notifications that it sends out. The user may miss something important, if they previously clicked DENY. For other applications, you might want to leave Notification decisions to the user.
2. How do I reset or clear out previous Notification Settings?
How do you reset Catalina’s Application Notifications if you clicked Allow or Deny already?
The settings are stored in a plist in the users /Library/Preferences folder.
com.apple.ncprefs.plist
To reset all Notification Alerts, you can delete the plist and then restart. Once you get back to the desktop all your notifications will start popping up again.
3. How can I test the Notifications Profile?
After you create the profile and install it, any open notifications will immediately disappear! The best way to test your new profile is to delete ncprefs.plist, then restart. Then you can leave any open notifications up on your desktop. Install the profile , then all the notifications that you manage should disappear.
4. Find Previous Bundle ID or Application Domains from past Prompts
If you want to see previous prompts that you have already answered try this command.
sqlite3 "$(getconf DARWIN_USER_DIR)/com.apple.notificationcenter/db2/db" "select * from app;"
4. Manage Notifications with a Profile.
The easiest way to manage Notification is with a Configuration Profile.
NOTE: If you use Jamf Pro, Notifications is not an option yet in 10.15.1.
I will show you two ways to create a Notifications Profile.
Creating Profiles is easy with Profile Creator! The version that we will be using is v0.3.2 which has Catalina Options built right in. After installing you will see the welcome screen.
Profile Creator’s Welcome Screen.
You can start by filling out the General Settings. Set the Name of the profile, Description, Company Name and Payload Scope. For the Payload Scope select System if you want the settings to be for all users. You can add Prevent users from removing this profile (Supervised)
Profile Creator’s General Settings.
Once you have the General Settings set you can add a new profile payload. Scroll down on the left hand side until you see macOS. You will then see Notifications.
Profile Creator Notifications Payload.
To start you will need to add the Notifications Payload Key. Click the + button on the left hand side of Notification Settings.
Profile Creator’s Notifications Payload Settings.
Now that Notifications Settings is active you can add new keys. Click the + button to add a new Key.
Profile Creator’s Notifications Key
Now you can view the different settings you can set.
1. Enable Notifications
2. Bundle Identifier for the target app
3. Show app in Notifications Center
4. Show Notifications at the Lock Screen
5. Notification Sounds Allowed
6. Allow Badges
7. Alert Type – None, Banners, Alerts
8. Enable Critical – If the banner can pass through DND
The option that you will need to find is the Application Bundle Identifier. An example would be Microsoft Outlook. The Bundle ID for Outlook is com.microsoft.outlook. How do you find the Bundle ID ?
You can find many ways to find the Application Bundle ID. I will show you 3 different ways to do this. One of the best ways is to look directly at the application info.plist. Run the following all on one line. Let’s check to see what Safari’s Bundle ID is.
Now that you have the Bundle ID, plug it into the 2nd box in the key options.
Profile Creator’s Notifications Key Application Bundle ID
You can now add as many keys as you want!
Profile Creator’s Notifications 2nd Key Application Bundle ID
Once you have finished adding all the Bundle ID’s you are ready to Add this payload to the main Profile and save it. Click the Add Button in the upper right hand corner.
Profile Creator’s Notifications Add NotificationsSettings to the main Profile.
You should now see this in the upper left hand corner.
Profile ready to save!
Now click on the upload button on the right hand side of the + button to save your new profile.
Profile Creator’s Save Menu
This is the save menu. Check over the settings to verify everything is correct.
NOTE: Just as the note says at the bottom. If you use Jamf Pro you need to Sign the profile with your Apple Developer ID. If you use any other MDM you do not have to do this.
You will now have a file called 10.15 Notifications.mobileconfig
You can now upload it to your MDM Server.
After installing the profile you can go into system preferences > Profiles and view the new profile. It will look something like this.
Notifications Profile Settings.
You can then scroll down to verify all the macOS Catalina Application Notifications settings.
6. Notifications Profile with Manage App Notifications.bash
William Smith aka (talkingmoose) just wrote an amazing bash script that will generate a Notifications.mobileconfig
The only limiting part of this script is that you can only set one application per profile. William has mentioned that he might look into adding the ability to add multiple application notification settings into one profile. If you would like this, please send him this feedback!
7. Credits
A big Thank You goes out to the following MacAdmins.
@stevemasser – For finding the Notifications Preference plist Location.
@roberthammen & @emily for Confirming that current notifications will disappear immediately when the profile is installed.
@eholtam for finding the neat sqlite3 trick for showing previously answered notifications.

Downtime
With Screen Time, you can schedule downtime so you (or your child) can only use specific apps you’ve approved.

With App Limits, you can set the amount of time you want to use your apps and websites. Set App Limits for total time, categories, or specific apps.

Create combined limits with a combination of app categories, specific apps, or websites.

When a limit is met, you can tap “One more minute” to give you time to quickly save your work or wrap up a conversation.
Communication Limits let you control who your children can communicate with and who can communicate with them throughout the day and during downtime.
Managed contact list for children
Parents can use Screen Time to manage the contacts that appear on their children’s devices.
Family Sharing
Parents can configure Screen Time from any device — iPhone, iPad, or Mac — and have everything set up for their kids on all their devices.
Security
Enhanced Gatekeeper
Gatekeeper will ensure that all new apps you install — from the App Store or the internet — have been checked for known security issues by Apple before you run them the first time and periodically thereafter. This extends the protection from the app’s source to include automated checks for what’s in the app.
Data protections
macOS Catalina checks with you before allowing an app to access your data in your Documents, Desktop, and Downloads folders; iCloud Drive; the folders of third-party cloud storage providers; removable media; and external volumes. In addition, you’re asked before an app can perform key logging or capture a still or video recording of your screen.
Activation Lock
All Mac models with the Apple T2 Security Chip now support Activation Lock — just like your iPhone or iPad. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you.
Dedicated system volume
macOS Catalina runs in a dedicated, read-only system volume — which means it is completely separate from all other data and helps improve the reliability of macOS.
DriverKit and user space system extensions
Previously many hardware peripherals and sophisticated features needed to run their code directly within macOS using kernel extensions, or kexts. Now these programs run separately from the operating system, just like any other app, so they can’t affect macOS if something goes wrong.
Find My
Two great apps in one
Find My iPhone and Find My Friends are now combined in a single, easy-to-use app to help you locate the people and devices that are important to you.
Find offline devices
Locate a missing device even if it’s not connected to Wi-Fi using crowd-sourced location. When you mark your device as missing and another Apple user’s device is nearby, it can detect your device’s Bluetooth signal and report its location to you. It’s completely anonymous and encrypted end-to-end, so everyone’s privacy is protected.
Enhanced location notifications
Location notifications include the ability to schedule notifications for different days of the week, more useful place names, and enhanced privacy controls.
Approve with Apple Watch
View passwords
Anywhere you need to type your Mac password, such as viewing passwords in Safari preferences, you can now double-click the side button on your Apple Watch to authenticate on your Mac.
Approving app installations
Unlock a locked note, approve app installations, unlock settings in System Preferences, and modify root files, all with your Apple Watch.
Accessibility
Voice Control
Voice Control is a new way to fully control your Mac, iOS, and iPadOS devices entirely with your voice.
Voice Control improves on the existing Enhanced Dictation feature using the Siri speech recognition engine, so you get the latest advances in machine learning for audio-to-text transcription.
Add custom words
Whether you’re writing a biology report, filling out a legal document, or emailing about a favorite topic, you can add custom words to ensure that Voice Control recognizes the words you commonly use.
On-device processing
All audio processing for Voice Control happens on your device, ensuring that your personal data is kept private.
Rich text editing
Thanks to rich text editing commands, you don’t have to rehearse before you speak. Making corrections is quick and easy. You can replace phrases by name. Try saying “Replace I’m almost there with I just arrived.” Fine-grained selection also makes it simple to select text. Try saying “Move up two lines. Select previous word. Capitalize that.”
Word and emoji suggestions
If you need to correct a word, there’s a new interface just for that. Simply ask to correct a word, and you’ll be presented with a list of suggested replacements.
Seamless transitions from dictation to commands
Voice Control understands contextual cues, so you can seamlessly transition between text dictation and commands. For example, say “Happy Birthday. Tap send.” in Messages, and Voice Control sends “Happy Birthday” — just as you intended. You can also say “delete that”, and Voice Control knows to delete what you just typed.
Comprehensive app navigation
You can rely entirely on your voice to navigate an app. Comprehensive navigation is provided by navigation commands, names of accessibility labels, numbers, and grids.
Navigation commands
Navigation commands give you quick ways to interact with macOS and apps. You can open apps, search the web, open Spotlight, and more.
Names
You can easily navigate by telling Voice Control to select the name of an accessibility label for buttons, links, and more.
Numbers
Say “show numbers” to see numbers appear next to all clickable items onscreen. Use this to quickly navigate complex or unfamiliar apps. Numbers automatically appear in menus and whenever you need to disambiguate between items with the same name. Just say a number to click it.
Grids
If you ever need to touch a part of the screen that doesn’t have a control, use Grid overlays. Saying “show grid” superimposes a grid on your screen and allows you to precisely do things, like select, zoom, drag, and more.
Hover Text
Hover Text displays high-resolution zoom of text, text fields, menu items, buttons, and more in a dedicated window. Just press the Control key when hovering over text with your cursor, and a window with zoomed text appears alongside the standard interface — helping you stay contextually aware. Text is crisply displayed in a font and color of your choice. And you can interact with buttons and type right in the zoomed window.
Zoom Display
While using a second display, you can see the same screen up close and at a distance simultaneously. You can keep one monitor zoomed in and another at a standard resolution. Or keep a personal Mac zoomed in while giving a presentation.
Simplified tab navigation
VoiceOver users will enjoy simplified keyboard navigation that requires less drilling into unique focus groups. The Tab key more simply advances through selection of elements — such as window stoplights, toolbar buttons, and scroll bars.
Punctuation in iCloud
VoiceOver users often customize the way punctuation marks are spoken. These customizations are now stored in iCloud, giving you a consistent experience across macOS, iOS, and iPadOS.
Additional international braille tables
macOS Catalina adds more international braille tables and lets you quickly switch between them.
Improved VoiceOver support in Xcode
VoiceOver now reads aloud warnings, line numbers, and breakpoints in the Xcode text editor.
Display color filters
Users with color vision deficiencies can adjust display colors using new color filter options. Your Mac shifts the colors onscreen, helping you easily differentiate areas of confusion. And you can turn this preference on and off through the Accessibility Options pane using Command-Option-F5.
Tint your entire display
A new display option lets you tint your entire screen using a color of your choice. Some users may find that certain color tints help make text easier to read.
Apple ID Account Information
One place for your Apple ID account details
Now you can access all your important Apple ID account information right from System Preferences on your Mac.
Overview and helpful notifications
A new overview pane allows you to quickly review important tips and notifications to help ensure that your account is properly signed in and secure, and that all the features you expect are set up and working correctly.
Basic account and security details
Easily review account details such as your name, contact info, password, security details, payment and shipping info, and email newsletter preferences.
iCloud settings
Review and update your iCloud settings and manage or upgrade your storage plan anytime.
Media and purchases
Get easy access to your current subscriptions, past purchases, and account settings related to the App Store, iTunes Store, Apple Music, Apple Books, Apple News, Apple TV, and more.
Family Sharing
View which subscriptions you’re sharing, which services are enabled, who has Ask to Buy turned on, and more.
View all your devices
View a list of all the devices you’re signed in to with your account. Review device details such as last backup completed, Find My status, and more.
QuickTime Player
Picture in Picture (PiP)
With a single click in the navigation controller, you can play video in a resizable window that isn’t blocked by other windows, allowing you to watch while working on other things.
Enhanced Movie Inspector
The Movie Inspector pane shows you even more in-depth technical information about the currently open media file. See key details such as video color space, HDR format, bit depth, scale, and aspect ratio.
Open Image Sequence
Create an H.264, HEVC, or ProRes-encoded movie file by navigating to a folder of sequentially numbered images, then choosing your desired resolution, frame rate, and encoding quality.
Timecode support
When QuickTime Player opens a media file with embedded timecode, it shows the time information in the onscreen navigation controller.
Transparent video support
Transparency in ProRes 4444 files can optionally be preserved when exporting to the HEVC format.
Home
HomeKit Secure Video
With a home hub such as an Apple TV or HomePod, securely record video to iCloud when activity by a person, animal, or vehicle is detected by your HomeKit-enabled cameras. Choose to receive notifications when clips are recorded and view them in the Home app on your Mac. In the Home app, a timeline of recordings is available to play from iCloud. You can also share a recording, delete it, or save it to your Photos library.
Audio in scenes and automations
HomePod and AirPlay 2–enabled speakers can now play songs, playlists, and radio stations from Apple Music in scenes and automations with your other HomeKit accessories.
International Features
New multilingual setup for macOS
Choose your languages, including those for keyboard and dictation, in Setup Assistant, and customize your language preferences from the start.
New relationship labels in Contacts
Contacts now includes hundreds of new, more specific relationship labels to help you manage your contact list. Examples include “younger cousin” and “elder cousin.”
Cantonese keyboard predictions
The new Cantonese predictions for Traditional Chinese Cangjie, Sucheng, Stroke, and Handwriting keyboards bring more relevant character and emoji predictions to Cantonese users.
Improved Japanese predictions
A new neural language model takes words typed earlier in the sentence into account, so predictions are more grammatically consistent and relevant to the subject matter.
New fonts for Indian languages
Get 34 new fonts, including four system fonts and 30 document fonts, for languages like Gujarati, Hindi, Kannada, Odia, Punjabi, and many more.
New Indian English Siri voices
All-new Indian English male and female Siri voices allow Siri to be more natural and expressive.
New dictionaries
New dictionaries include Thai-English and Vietnamese-English.
You can now share folders with a private link. Anyone who has access can see the folder in iCloud Drive, add new files, and get the latest versions of files.
Restore from snapshot
If your third-party software is incompatible with an update you just installed, use macOS Recovery to restore from a snapshot of your computer taken right before the installation. macOS and all your apps will work just as they did before you installed the update.

The Xcode 11 Gold Master version of Xcode is ready! Usually GM or Gold Master means that this Build Version is the final shipping version. Apple still may release another update so don’t bank on this being the final version.
This article is meant to save you time going through the notes to find what is new and what is still leftover from the last beta. I went through both Beta 7 and the new New Xcode 11 GM (11A419c) release notes to find all the changes. I also included the entire patch notes list as an archive. When Apple releases new patch notes the previous patch notes are overwritten and taken down.
Summary of New Xcode 11 GM Seed 1 Patch Notes
26 New Features
25 New Resolved issues
15 New Known Issues
2 New Deprecations
A Full List of changes is listed below, along with the full patch notes list.
The new Xcode 11 is available in the Mac App Store and includes SDKs for iOS 13, macOS Catalina 10.15, watchOS 6, and tvOS 13. Xcode 11 supports development for devices running iOS 13.1. Xcode 11 supports on-device debugging for iOS 8 and later, tvOS 9 and later, and watchOS 2 and later. Note that Xcode 11 requires a Mac running macOS Mojave 10.14.4 or later.
1. New Features in Xcode 11 GM
Asset Catalog – Xcode can find assets in your workspace/project using the Find navigator. The Asset Catalog Editor also supports Find and Replace, and you can rename assets using Replace. (14279237)
Build System – Xcode uses response files by default to pass input files to the Swift compiler. To turn this behavior off, set USE_SWIFT_RESPONSE_FILE to NO. (50852028)
Build System – Projects may now use custom build rules by setting the ‘Process Header Files’ (APPLY_RULES_IN_COPY_HEADERS) build setting to YES. (48185100)
Build System – An XCFramework makes it possible to bundle a binary framework or library for multiple platforms —including iOS devices, iOS simulators, and Mac Catalyst — into a single distributable .xcframework bundle that your developers can use within their own applications. An .xcframework bundle can be added to an Xcode target’s Link Libraries phase and Xcode uses the right platform’s version of the included framework or library at build time. Creation of frameworks is supported from the command line using xcodebuild -create-xcframework. Frameworks or libraries bundled in an XCFramework should be built with the Build Libraries for Distribution build setting set to YES. (49948269)
Create ML – A Tabular Regressor template is now available, joining Image Classification, Sound Classification, Activity Classification, Tabular Classification, Word Tagger and Text Classification. (54005628)
Debugging – Override system settings like appearance, dynamic type, and accessibility options for the debugged process using Environment Overrides, accessible from the debug bar. (45848655)
Debugging – Xcode can prefer using Wi-Fi to connect to a Watch when installing or debugging an app. (50313856)NoteThe iPhone-Watch pair must be on the same 2.4 GHz network. Networks that block peer-to-peer connections cannot be used.
Debugging – LLDB’s Python scripting is now based on Python 3. If you are using Python extensions that aren’t compatible with Python 3, they will break. To help with the transition, you can run in Python 2 mode by setting a default:defaults write com.apple.dt.lldb DefaultPythonVersion 2 Python 2 support will be removed in the future. (47806994)
Debugging – Swift Decimal values have a data formatter in LLDB, making them display in a readable way. (38983073)
Localization – The manual page for genstrings documents its behavior in more detail. (19709369)
Organizer – The new Metrics organizer shows battery life and performance analytics for your app to help you drive optimizations. Metrics are reported for your app when distributed on the App Store and after sufficient field use. The available metrics are battery drain, launch time, hang rate, memory, and disk writes. You can filter data by device and usage characteristics. (43028903)
Playgrounds – SwiftUI live views and inline results in playgrounds are supported. (42226387)
Server – Xcode Server now supports Mac Catalyst apps. (50602873)
Simulator – Metal is available in iOS 13 and tvOS 13 simulators when running on macOS 10.15. Metal code is executed on the host Mac GPU, and is significantly faster than simulated OpenGL code. (System APIs in watchOS 6.0 simulators are also GPU accelerated.)The APIs in SceneKit, CoreAnimation, and other system frameworks abstract many differences between GPUs, reducing the need for device-specific code. When running on earlier versions of macOS or in an environment where Metal is not available, simulators continue to use software rendered OpenGL. If your Mac has multiple GPUs, use the File menu in Simulator to select which GPU to use. If the GPU in use becomes unavailable, any simulators using it automatically shut down. (18430676)
Simulator – Xcode no longer creates every available iOS simulator device by default. Instead a set of the most commonly used devices are created. To create other devices — or multiple instances of a device — open the Devices window, select Simulators, click the + button, enter a name, and select the relevant device type and OS version. In Terminal, execute the xcrun simctl create command, for example xcrun simctl create “My iPhone 7” “iPhone 7” iOS13.0. (49428617)
Simulator – iOS 13, watchOS 6, and tvOS 13 simulators now have a dyld shared cache. This improves simulator launch times and reduces the number of open file handles used by simulator processes. If you report an issue you believe is related to the shared cache, include a simctl diagnose and the output of launching your program with DYLD_PRINT_LIBRARIES=1. (13632739)NoteA missing symbol crash may now mention the shared cache but this is not a shared cache bug. The message is merely informing you that the shared cache was consulted when searching for the symbol.
Source Editor – Xcode 11’s source editor introduces a mini-map of the file. The mini-map includes legible text for Mark:, highlighted lines with errors and warnings, source control changes, breakpoints, and highlighted Find results. The mini-map is enabled by default and can be turned off per editor. (35939517, 46064742, 46064809, 46064921, 46064981, 47127500, 47208960, 47516881)
Source Editor – Added options to control the indentation of case labels inside switch statements. This can be controlled separately for Swift and C-family languages under Preferences -> Text Editing -> Indentation. (9441571)
Source Editor – Added an option for controlling indentation inside the C++ namespace and external C blocks in Preferences > Text Editing > Indentation. (20700010)
Source Editor – Pasted text is no longer re-indented by default, though the initial whitespace is adjusted to match the surrounding text. This can be controlled with Preferences > Text Editing > Indentation. (16047992)
Source Editor – Added support for syntax coloring YAML files. (19942196)
Swift – The @frozen attribute for structures and enumerations is now available. (SE-0260, 36597490)
Swift – More thorough checking has been implemented for restrictions around escaping closures capturing in-out parameters or values of noescape type. While most code isn’t affected, there are edge cases where the Swift 5.0 compiler accepted code that violated these restrictions. (SR-8546, SR-9043, 43355341)An example of invalid code which was incorrectly accepted by the Swift 5.0 compiler is an @escaping closure that calls a local function that references an in-out parameter from an outer scope:struct BadCaptureExample { var escapingClosure: () -> () mutating func takesInOut(_ x: inout Int) { func localFunction() { x += 1 } escapingClosure = { localFunction() } } } The compiler now correctly diagnoses the above code by pointing out that the capture of x by localFunction() is invalid, since localFunction() is referenced from an @escaping closure.This also addresses certain cases where the compiler incorrectly diagnosed certain code as invalid, when in fact no violation of restrictions had taken place. For example:func takesNoEscape(_ fn: () -> ()) { func localFunction() { fn() } { localFunction() }() }
Swift Packages – Xcode now supports creating and working with Swift packages, as well as adding, removing, and managing package dependencies. The package management support in Xcode is built on top of the open source Swift Package Manager project. (22427200)
Testing – XCTest includes augmented performance testing capabilities with the new measure(metrics:options:block:) method and related methods. The metrics argument requires a list of objects conforming to the XCTMetric protocol. You can either implement your own custom metrics or use XCTClockMetric, XCTOSSignpostMetric, XCTCPUMetric, XCTMemoryMetric, or XCTStorageMetric. (49430032)The following shows an example performance test that measures the CPU and Memory impact of sorting a list:func testExample() { // Measures the CPU and memory impact of sorting the input list. measure(metrics: [XCTCPUMetric(), XCTMemoryMetric()]) { sortedList = qsort(list: self.fiftyNumbersFrom0to100) } }
Testing – When running tests using a test plan, it is now possible to configure which targets to include in code coverage results via the test plan’s code coverage setting. (53504451)
2. New Resolved Issues in Xcode 11 GM
General – Fixed an issue where issue text may appear light when using a light theme with a dark system appearance. (48230278)
Create ML – Non-ASCII characters can be used as training labels for Image Classification and Sound Classification. (53594243)
Debugging– Breakpoints support the VoiceOver command to open the shortcut menu. (44940944)
Debugging – Redeclaring self in Swift code works properly with LLDB. (39611934)
Debugging – The Swift REPL and LLDB’s python scripting work properly when the python binary in PATHisn’t the system one. (40961425)
Interface Builder – Fixed an issue where system colors in XIB files set to deploy before iOS 13.0 wouldn’t adapt to the system appearance at runtime. (54362252)
Debugging – Resolved an issue that prevented running a Watch App that has the ‘Supports Running Without iOS App Installation’ setting on a pre-watchOS 6.0 device or simulator. (54104164)
Simulator – Fixed an issue that could cause Simulator to crash or become unresponsive following clipboard-related actions in other applications if automatic pasteboard synchronization is enabled. (54011137)
Simulator – Changing the audio in a simulated device while a video is playing in Safari won’t mute the audio of the video. (51207286)
Source Editor – Fixed an issue where double clicking on a C++ destructor name would also select the tilde (~). (6368356)
Source Editor – Makefiles are now correctly recognized, and are always indented using tab characters. (16975247)
Source Editor – Fixed an issue where changing a file’s tab width would not update the display. (52026893)
Source Editor – When full lines are selected, typing a delimiter now places the delimiters on separate lines, shifting the selection to the right. (52077437)
Source Editor – Fixed a problem where double-clicking text containing words separated by periods in comments would select too much. (11541526)
Source Editor – Double-clicking the quotes of a Swift string containing interpolations now selects the whole string. (24470374)
Source Editor – Improved the recognition of functions in shell script files. (52478049)
Source Editor – Improved performance and correctness when parsing XML and HTML files. (50672550)
Source Editor – Improved the syntax coloring for man page files. (52035097)
Swift – Static libraries are now always force-loaded in their entirety during linking, fixing most “unable to demangle” runtime errors. (47598583)
Swift – If a type has the same name as its containing module, importing that module from a module interface works properly. (19481048, 48445154)
SwiftUI – The #if/#endif compiler conditionals surrounding PreviewProvider types have been removed from SwiftUI templates. PreviewProviders aren’t properly removed from built products when archived. (51539802)
SwiftUI – Xcode Previews work when your built products (derived data) are on a separate volume from your home directory. (54327360)
SwiftUI – Switching run destinations will show the correct device in Xcode Previews. (54006837)
SwiftUI – Fixed an issue preventing Xcode Previews from working for macOS apps with App Sandbox enabled. (51088926)
Testing – The unit test discovery mechanism is more efficient for large projects. The test navigator gets populated faster after reopening a project. (32567980)
3. New Known Issues in Xcode 11 GM
General – When building an Objective-C iOS File Provider application extension that implements the URLForItemWithPersistentIdentifier method, Xcode emits a warning saying that this callback method is deprecated and won’t be called. This warning is incorrect; the method isn’t deprecated, and is called at the appropriate times. (54487300)
Asset Catalog – Named colors in the asset catalog won’t be found at runtime when running on iOS 11. (54325712)
Command Line Tools – When using the Command Line Tools as the active Developer directory, some users may experience random crashes in the Swift compiler. (53582696)Workaround: Execute the command sudo rm -f /Library/Developer/CommandLineTools/usr/lib/swift/macosx/libswift*.dylib in Terminal.
Create ML – Apps importing the Create ML framework may not launch if they are compiled by Xcode 11. This doesn’t impact existing apps. (53795065) Workaround: Add the file libswiftCreateML.tbd in the ‘Link Library with Libraries’ section.
Reality Composer – The Rename menu item isn’t enabled when scene, object, or behavior is selected. (54274819)Workaround: You can rename scenes and objects using the Name field in the Properties inspector. You can rename behaviors by right-clicking the behavior and selecting Rename from the contextual menu.
Simulator – iCould Drive isn’t supported in iOS 13.0 and earlier simulator runtimes when running on macOS Catalina 10.15. Logging into iCloud on impacted simulators will result in birdterminating and relaunching in a cycle. (51392951)Workaround: Log out of iCloud in impacted simulators to halt the crash cycle.
Simulator – Simulated devices running iOS 13 may fail to enable an external display or CarPlay display, instead displaying a black window. (53966664)Workaround: Close the window and try again. If that fails restart the affected simulator.
Simulator – When running UI tests in a simulated device on a macOS host with slow hardware the test runner process may get killed by the CPU watchdog. (54136015)Workaround: Free up resources so the simulated device has faster I/O. You can also extend the watchdog timeouts by setting a user default in the relevant simulator. Boot the simulator, then run:xcrun simctl spawn defaults write com.apple.springboard FBLaunchWatchdogScale 2 This must be set on each simulator. Erasing a simulator will reset this setting.
Simulator – Attempting to create an MIDINetworkSession in a simulated device running iOS 13 won’t succeed. (54484923)
SwiftUI – The attribute inspector doesn’t allow specifying flexible frames. (51310989)Workaround: Use the source editor to work with the frame inspector when specifying flexible size information.
SwiftUI – Text view doesn’t display properly in tvOS playgrounds. (54148259)
SwiftUI – SwiftUI has an API that lets you change the value type of Binding to AnyHashable:let someBinding: Binding = … let typeErasedBinding = Binding(someBinding) Attempting to use this API fails at compile time with a linker error on watchOS 6. (53769896)
SwiftUI – Apps containing SwiftUI inside a Swift package crash on launch on devices running iOS versions earlier than iOS 13. (53706729)Workaround: When back-deploying to an OS that doesn’t contain the SwiftUI framework, add -weak_framework SwiftUI to the Other Linker Flags setting in the Build Settings tab. See Frameworks and Weak Linking for more information on weak linking a framework. Note that this workaround doesn’t apply when using dynamically-linked Swift packages which import SwiftUI.
SwiftUI – Xcode Previews fast turnaround may not work in some files. (48091832)Workaround: If you encounter issues using Xcode Previews, you can try disabling hot-swapping per file using the Editor > Previews menu. You will still be able to use previews, but without the faster turnaround that hot-swapping provides.
Swift Compiler – Applying multiple property wrappers to a property could cause the compiler to synthesize accessors with the wrong ABI. This feature has been disabled to prevent incompatible ABI changes from occurring in the future. (53428736)
4. New Deprecations in Xcode 11 GM
Command Line Tools – Command line support for Subversion will be removed in a future release. (50195246, 50231958, 50266910, 51740851, 52528748)
Debugging – Starting in macOS 10.15, the Quartz Composer framework is marked as deprecated, but remains present for compatibility purposes. Transition to frameworks such as Core Image, SceneKit, or Metal if your app is using Quartz Composer. (50911608)
