Month: July 2019

Today Apple released macOS Catalina 10.15 (19A501i) Beta 3 to Developers.

MacOS Catalina 10.15 (19A501i) Beta 3 was released today July 2nd, 2019 at 12:00 CST. This time around I have included a summary of what’s new/changed in Beta 3 compared to Beta 2. Like usual, I also have included the entire patch notes list.

Summary of Beta 3 Changes

This is a summary of changes from 10.15 Catalina Beta 2 – Beta 3.

• 0 New Deprecations
• 1 New Feature
• 7 New Known Issues
• 29 New Resolved issues

1. Beta 3 New Features

• SwiftUI – You can style a NavigationView using two new style properties: stack and doubleColumn. By default, navigation views on iPhone and Apple TV visually reflect a navigation stack, while on iPad and Mac, a split-view styled navigation view displays. (51636729)When using the doubleColumn style, you can provide two views when creating a navigation view — the first is the master and the second is the detail. For example:NavigationView { MyMasterView() MyDetailView() } .navigationViewStyle(.doubleColumn)

Report your bugs NOW!

Now that 10.15 Beta is live, be sure you begin testing as soon as you can. You will want to get any bugs that you find into Apple now. If you get them in now, they could be fixed in the current beta cycle instead of waiting until after September’s release date. If you wait it could be months before the fix is put into a dot release combo update.

Full 10.15 (19A501i) Beta 3 Patch/Release Notes

I always post the full patch notes to this page to document them for you. The reason behind that is that Apple will usually just replace over the old patch notes so you are then unable to see what was fixed in the previous release.

Overview

The macOS 10.15 SDK provides support for developing apps for Macs running macOS Catalina 10.15. The SDK comes bundled with Xcode 11 beta available from Beta Software Downloads. For information on the compatibility requirements for Xcode 11, see Xcode 11 Beta 3 Release Notes.

General

New Features

Known Issues

• Under certain conditions, your iCloud Drive might be missing data after upgrading to macOS Catalina beta.Workaround: Recover deleted files on iCloud.com. (51787170, 51950018)
• Certain documents might not download in iCloud Drive. (52295165)
• The Cloud Files section in About This Mac > Storage > Manage might inaccurately represent the current state of files on your Mac. (50362095)
• Even when Optimize Storage is switched off, iCloud Drive might fail to automatically download all files. (50667204)Workaround: Download files individually.
• When creating a new Pages, Numbers, or Keynote document in a shared folder, you might see the message “Couldn’t connect to iCloud”. (50827963)Workaround: Close and reopen the document.

Resolved Issues

• There are no longer multiple empty Application libraries within iCloud Drive. You can safely remove any empty folders. (51635803)
• The content of folders inside an iCloud Shared Folder is available to other users viewing your shared folder. (51591135)
• Turning off the Siri switch in iCloud settings correctly stops Significant Locations from syncing. (50908297)
• Pages, Numbers, and Keynote documents in shared folders correctly show an error message when you try to access them from iCloud.com. (50738067)

iPad Apps on Mac

Known Issues

• MPMediaPickerController might not display the contents of your library. (51785735)
• macOS and iPad Apps on Mac are currently view-only clients of PencilKit. (51146823)
• In order to show a share sheet from a toolbar item using the UIActivityViewController, create the NSToolbarItem using the init(itemIdentifier:)initializer and pass it a UIBarButtonItem configured as a UIBarButtonItem.SystemItem.action. There is no need to set the barButtonItem property. (47292316)
• The UIScreen class’s isCaptured API isn’t currently supported. (48360589)
• The current property on UIDevice and the OS Product Name is currently returned as iOS rather than macOS, which can affect diagnostic logs generated by your system. (49792004)
• Event handling in extension contexts may produce unexpected results, including failure to deliver trackpad pinch and zoom gestures. (50145462)
• When sending Mail attachments via MessageUI, each attachment might appear as two icons when viewed by the recipient. (50369995)
• Controls drawn with accent color incorrectly maintain their active color when the window is inactive. There is no need to work around this in your app. (50563638)
• The UIKit module currently doesn’t import the newly added NSToolbar and NSTouchBarheaders, NSToolbar+UIKitAdditions.h and NSTouchBar+UIKitAdditions.h. You can import these headers directly in Objective-C, or you can create a bridging header to import them for Swift. Be sure to import Foundation before importing these headers. (50704322)
• When your iPad App on Mac is launched directly into the background, it experiences all the state transitions of a regular app launch — such as application(_:didFinishLaunchingWithOptions:) and applicationDidBecomeActive(_:) — followed by state transitions to return to background state from there — applicationWillResignActive(_:) and applicationDidEnterBackground(_:). This will soon be updated to match iOS, where your app will receive only applicationDidFinishLaunching(_:), and only if it wasn’t already running. (50742219)
• For iPad Apps on Mac to save to Photos Library, explicitly linking the Photos framework is required. (50781430)
• Opening a CloudKit share URL might not launch an iPad App on Mac that’s present on the system. Additionally, the system might not take the user to the appropriate App Store page to download an app which isn’t present on the system. (50877241)
• Action and share extensions might exhibit visual anomalies. (51005363)
• All assets at 3x scale factor are currently ignored when compiling the asset catalog for iPad Apps on Mac. Because the search begins with the universal asset, assets for a specific memory or graphics class won’t be found. For example, if you provide an image and only give a 6GB and Metal 5v1 asset, it won’t be found at runtime. It’s recommended that you provide all images as vectors to allow generation of the correct scale factors, or at minimum provide 2x versions of the assets. If you’re classifying resources based on memory and graphics families then you should provide “Any Memory” and “Any Graphics”. (51033745)
• CallKit CXAction instances might return an error. (51074735)
• If your iPad App on Mac is launched directly into the background, a second background launch request launches the app into the foreground, making it visible to the user. If your app uses any of the supported APIs which might result in a background launch, this might cause your app to launch in the foreground without user input. (51287556)
• In macOS 10.15 beta, the UIGraphicsRenderer class’s default() function returns the nonextended color range renderer format by default. To use-extended color range format for rendering, create an instance using preferred() and pass it to init(bounds:format:). (51303954)
• When creating a Mac version of your iPad app, Xcode automatically generates a unique Mac bundle identifier. If you have an existing Mac bundle identifier you’d prefer to use, you can do so by using manual signing in Xcode. (51076014)Follow these steps to configure your project, AppID, and provisioning profile:

1. Sign in to Apple Developer, then select Certificates, Identifiers, and Profiles.
2. In the Identifiers section, select your iOS app identifier to edit.
3. Check the UIKit for Mac capability to enable it, then click the Configure button.
4. Choose Use an existing macOS AppID and select the identifier you’d like to use from the popup menu. Click the Save button to finish editing your AppID.
5. In the Profiles section, click the + button to create a new profile, select ‘macOS App Development’, and click Continue.
6. Select your iOS AppID from the popup, click Continue, and complete the rest of the profile creation flow. When finished, click the Download button.
7. In Xcode, select your project to view the Project Editor and select your app’s target. Then select the Build Settings tab.
8. Set the Derive UIKit for Mac Product Bundle Identifier setting to No.
9. Expand the Product Bundle Identifier build setting to view its configurations. Next to the Debug configuration, click the + button to add a conditional value.
10. For the build setting condition, select Any macOS from the popup menu. Edit the value of the conditional build setting to match the macOS bundle identifier you want to use. Repeat this step for all configurations in your project.
11. In the Signing & Capabilities tab, uncheck Automatically manage signing.
12. For your macOS app, select Import Profile from the Provisioning Profile popup and then select the profile you downloaded earlier.

Resolved Issues

• You can now import AppKit and UIKit modules in the same compilation unit. (48094910)
• The completion handler is no longer invoked with an error when donating interactions using the INInteraction class on macOS. (48371526)
• The productsRequest(_:didReceive:) method from StoreKit currently returns with didFailWithError and products aren’t loaded. (51028870)
• MTKView objects might render correctly. (51084042)

iWork

Known Issues

• Attempting to open iWork documents in Finder will unexpectedly create a .cpgz file if the corresponding iWork app isn’t installed. (40693892)Workaround: Install the corresponding app from the App Store before opening the document.

Localization

Known Issues

• Certain languages might exhibit clipped or misaligned layout. (51068688,50983852)
• Certain languages might display unlocalized text. (47765173,51196633)

Mail

Known Issues

• If your Mac contains both macOS Mojave 10.14 and macOS 10.15 volumes, you might experience issues searching in Mail. (46611310)Workaround: While running macOS Mojave 10.14, open Terminal and execute the following command:sudo touch /.metadata_never_index_unless_rootfs Reboot into macOS 10.15, open Terminal and execute the following command:sudo touch /System/Volumes/Data/.metadata_never_index_unless_rootfs Reboot into macOS Mojave 10.14, open Terminal and execute the following command:sudo mdutil -E / Depending on the size of your Mail database, it might take many hours to reindex all content.

Music

Known Issues

• Navigating using the back button might produce unexpected results. (51248128)
• Music might take a long time to launch for some users. (51207753)

Networking

New Features

• All NSURLSessionTasks with a GET HTTP method which contain a body will now produce the error NSURLErrorDataLengthExceedsMaximum. (46025234)

Known Issues

• An active Network Extension content filter configuration might interrupt the boot process indefinitely following a kernel panic. (50965627)Workaround: Boot into macOS Recovery, launch Terminal, and execute the following command:rm /Library/Preferences/com.apple.networkextension.necp.plist
• The NWEthernetChannel API doesn’t currently support VLAN interfaces. NEPacketTunnelProvider will see both tagged and untagged frames arriving on physical interfaces. Depending on the Ethernet driver, VLAN tags might be processed by hardware and thus stripped off the Ethernet frames thus NEPacketTunnelProvider won’t see the VLAN tag. (51275655)

Deprecations

• Support for FTP and File URL schemes for Proxy Automatic Configuration (PAC) is removed. HTTP and HTTPS are the only supported URL schemes for PAC. This affects all PAC configurations including but not limited to configurations set using Settings, System Preferences, profiles, URLSession APIs such as connectionProxyDictionary, and CFNetworkExecuteProxyAutoConfigurationURL(_:_:_:_:). (28578280)
• SPDY support is removed from the URLSession and NSURLConnection APIs. Servers should use HTTP 2 or HTTP 1.1. (43391641)
• The Network Kernel Extension API is now deprecated. (49284108)
• NetBIOS is disabled in macOS 10.15 to speed up mounting, browsing, and connecting to SMB shares. Some older printers and file servers may require NetBIOS to connect. (51119111)To enable NetBIOS, you can create or edit the /etc/nsmb.conf file. If your system doesn’t already have an /etc/nsmb.conf file, use the following Terminal commands while logged in as an Administrator:echo "[default]" | sudo tee -a /etc/nsmb.conf echo "port445=both" | sudo tee -a /etc/nsmb.conf To disable NetBIOS, you can safely delete the /etc/nsmb.conf file.

Photos

New Features

• To improve the Photos upgrade experience, Photos is testing database upgrades using a clone of the Photo Library. This clone doesn’t include the content of each photo, but does include faces metadata and a thumbnail image of each person in your library. It also contains metadata such as the asset name and the geographic location of the photo. It is created at ~/Pictures/macOS 10.15 Pre-Upgrade Backup, and you can manually remove this backup at any time. The clone will be removed automatically before the final release of macOS 10.15. (51033690)

Podcasts

Known Issues

• The sidebar might render unexpectedly until quitting and relaunching the app. (51340728)
• Deleting podcasts using About This Mac > Storage > Manage doesn’t update what’s shown in the Podcasts app until it’s relaunched. (50354510)
• Setting “Automatically Download Episodes” to “Never” might not take effect. (50960777)
• Writing a review isn’t currently supported. (46173722)
• Manually checking for feed updates when Option-clicking the Podcasts app in the dock isn’t currently available. (50958585)Workaround: Quit and relaunch the app.
• If Podcasts is placed in Full Screen mode, some UI elements might be obscured by the toolbar. (47125303)

Resolved Issues

• Browse and Top Charts consistently display content from the expected country. (51681853)
• A migration is no longer triggered even if there’s no content to migrate the first time you launch Podcasts. (51145044)

Quartz Composer

Deprecations

• Starting in macOS 10.15, the Quartz Composer framework is deprecated and remains present for compatibility purposes. Transition to frameworks such as Core Image, SceneKit, or Metal. (50911608)

Screen Sharing

Resolved Issues

• If the Mac you’re screen sharing with is running macOS 10.15 beta, you can now drag and drop onto the screen share. (50791710)

Screen Time

Known Issues

• Users can click ‘One more minute’ multiple times per day instead of only once each time they reach a limit for that app. (48773803)
• Screen Time > Content & Privacy > Content > Web Content > Allowed Websites Only isn’t currently enforced in macOS 10.15 beta. (50462899)

Scripting Language Runtimes

Deprecations

• Scripting language runtimes such as Python, Ruby, and Perl are included in macOS for compatibility with legacy software. Future versions of macOS won’t include scripting language runtimes by default, and might require you to install additional packages. If your software depends on scripting languages, it’s recommended that you bundle the runtime within the app. (49764202)
• Use of Python 2.7 isn’t recommended as this version is included in macOS for compatibility with legacy software. Future versions of macOS won’t include Python 2.7. Instead, it’s recommended that you run python3 from within Terminal. (51097165)

Spotlight

Known Issues

• Drives formatted using exFAT and FAT aren’t searchable using Spotlight. (52271781)
• Mail messages might not display previews. (35678035)

SwiftUI

New Features

• You can style a NavigationView using two new style properties: stack and doubleColumn. By default, navigation views on iPhone and Apple TV visually reflect a navigation stack, while on iPad and Mac, a split-view styled navigation view displays. (51636729)When using the doubleColumn style, you can provide two views when creating a navigation view — the first is the master and the second is the detail. For example:NavigationView { MyMasterView() MyDetailView() } .navigationViewStyle(.doubleColumn)

Known Issues

• Return types for View modifier methods include complex generic types. In a future release, these methods will return simpler types. (46140669)
• Image instances don’t use resizing information configured in asset catalogs. Configure the size of an image using the resizable(capInsets:resizingMode:) modifier instead. (49114577)
• A ScrollView doesn’t always size itself as expected for its content. (49204262)Workaround: Size the view that’s inside the ScrollView by applying the frame(width:height:alignment:) modifier to the inner view. (49204262)

Resolved Issues

• The tabItemLabel(_:) modifier — now named tabItem(_:) — now accepts @ViewBuilder closures. (51502668)
