10.15.5 & 10.15.4 = Wake from Sleep Kernel Panic on 16″ MBPro (2019)

MrMacintosh.com - Did you Install the 10.15.4 Update on your 16 Inch MacBook Pro 2019, only to get a Kernel Panic after you Wake it from Sleep? You are not alone. — The Catalina 10.15.4 Update is causing kernel panics in some 16″ 2019 MacBook Pros.

Did you Install the 10.15.4/10.15.5 Update on your 16 Inch MacBook Pro 2019, only to get a Kernel Panic after you Wake it from Sleep? You are not alone.

UPDATE 7/15/20 – The 10.15.6 update is live! mrmacintosh.com/whats-new-in-the-macos-catalina-10-15-6-update-19g73/ Let me know if the update fixes the issue for you!

UPDATE 7/09/20 – I have received word that the wake from sleep kernel panic issue is resolved in 10.15.6 Beta 4 GM (19G71a). If still have the issue and can test, please let me know.

UPDATE 6/25/20 – I have a few reports that Big Sur Beta 1 fixed the issue, but for others they can still reproduce the problem. I would not recommend installing Big Sur as your main OS. You can install it in a 2nd container or external hard drive for testing. If Big Sur fixes the wake from sleep crashing issue, comment below or let me know!

UPDATE 6/8/20 – I am looking further into the 10.15.5 reports. Looks like this is the common error “Sleep transition timed out after 180 seconds while calling power state change callbacks. Suspected bundle: com.apple.iokit.IOGraphicsFamily.”

UPDATE 6/03/20 – I am seeing new reports that the 10.15.5 Update has not fixed the issue for some users. Others are saying that after installing the 10.15.5 Update that they are no longer seeing Kernel Panics after waking from sleep. Additional reports are saying that the issue is worse after installing the 10.15.5 Supplemental Update.

UPDATE 5/26/20 – Apple just released the 10.15.5 update. Let me know if the 10.15.5 update fixes the issue for you!

UPDATE: 5/18/20 – It looks like 10.15.5 Beta 4 fixes the wake from sleep kernel panic issue. I have received multiple emails, tweets and article replies confirming that Beta 4 has fixed the issue for them. I would like to take the time to thank you for all of your individual reports. When I can’t reproduce the issue, I rely on you to provide critical feedback. THANK YOU!

UPDATE: 5/15/20 – I am starting to get some reports that the 10.15.5 Beta 3 & 4 fix the issue. Did you try the latest beta and find that it fixes the issue? Let me know!

UPDATE: 5/7/20 – macOS Catalina 10.15.5 Beta 4 (19F83c) was released today. I have not received any reports that Beta 3 fixed this issue. If it has please let me know. Apple did not mentioned this issue in any of the 10.15.5 Beta Patch Notes.

UPDATE: 4/29/20 – macOS Catalina 10.15.5 Beta 3 was released today. I am getting word that Beta 3 includes a possible fix for the wake from sleep issue. If you install Beta 3 and it fixes your issue, please let me know!

Main Article

As soon as the 10.15.4 Update hit, reports started to pop up of wake from Sleep Kernel Panics on the 16″ MacBook Pro. Does this situation sound familiar to you? If so you have a great memory! I tracked a very similar issue that was caused by the 2019-004 Mojave and High Sierra Security update back in July of 2019.

1. Affected Mac Models

Usually we have multiple different Models that are affected, but this time the issue looks to happen only one model.

MacBook Pro 16-Inch 2019
MacBook Pro 13-Inch 2020

2. Affected OS Versions

This issue affects 3 versions of macOS Catalina

1. macOS Catalina 10.15.4 (19E266)
2. macOS Catalina 10.15.4 Supplemental Update (19E287)
3. macOS Catalina 10.15.5 (19F96)
4. macOS Catalina 10.15.5 Supplemental Update (19F101)

3. Problem: Kernel Panic after waking from sleep.

I have collected and analyzed multiple Kernel Panic reports. This time, the issue can happen in mulitple situations.

Close lid and let the Mac Sleep – Open Lid = KP
Apple Icon to > Sleep – Hit key or move mouse = KP
The KP can happen with the MacBook Pro Plugged into Power or not.
KP Can also happen while connected to a Dock or Monitor.

5. Workarounds?

So far we at least 4 possible workarounds that have been posted.

1. Reset SMC (System Management Controller) NOTE: this only seems to help a very small handful of users.
2. Disable Sleep when on Power– Check the box “Prevent Computer from sleeping automatically when the display is off”
3. Disable Sleep when on Battery “Put hard disks to sleep when possible”
4. Disable “Enable Power Nap While Plugged into a power adapter” or “Enable Power Nap while on battery power”

6. Reverting back to 10.15.1, 10.15.2 or 10.15.3?

Sometimes reverting back to a previous version of macOS can resolve the issue until Apple Releases a fix. A perfect example is the 2015-2017 Macbook Air & 2015 13″ MacBook Pro 5th Gen Intel GPU Freezing Issue. The issue will only affect you if you have the 2020-002 Security Update Installed. If you revert back to the 2020-001 Update your mac will be fine.

So far I have not seen any reports. If you have reverted back and that fixed the issue for you, please let me know. Also let me know if you reverted back and you still have the issue.

7. This has happened before. Wait a few days before installing updates.

This is not the first time Apple has pulled an update. They pulled High Sierra and Sierra 2019-002 Security Update this past March. It’s a good idea to wait at least a few days before you update.

mrmacintosh.com/apple-replaces-2019-002-security-updates-for-10-13-and-10-12-bridgeos-updates-also-show-as-new/

Another example is the GPU Freezing Issue that I noted above

mrmacintosh.com/2020-002-update-causes-some-macs-to-freeze-when-using-video-conf-apps/

8. Does Apple Know about this issue? Are they working on a fix?

Apple does know about the problem. Engineering is currently investigating the issue. This information comes from MacAdmins who have a Enterprise Support Ticket in with Apple.

Hopefully we get a 2nd Supplemental Update that fixes the issue soon.

What’s New in macOS Catalina 10.15.2 Beta 1 (19C32e)

Today Apple released macOS Catalina 10.15.2 Beta 1 (19C32e) to Developers.

10.15.2 Beta1 is now live, so let’s dig in and see what changes Apple added to this new build 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. When Apple releases the next Beta patch notes, the previous patch notes are overwritten and taken down.

Summary of 10.15.1 Beta 3 Patch Notes

1 New Feature

Report your bugs NOW!

Now that macOS Catalina 10.15 is live you still will want to get any bugs that you find into Apple now. After the production release of the OS bugs can take longer to fix. The 10.14.4 “Update Keychain” bug is a perfect example.

What’s New in macOS Catalina 10.15 GM Seed #1 Beta 11 (19A582a)

UPDATE: 10/9/19 – macOS 10.15.0 is LIVE, What’s New? – mrmacintosh.com/macos-catalina-10-15-0-19a583

Today Apple released macOS Catalina 10.15 GM Seed #1 Beta 11 (19A582a)

Catalina 10.15 GM Seed #1 is here! GM stands for Gold Master, this term is from way back when CD and DVD media was still a thing. The GM build was the final production version of the OS burned to CD or DVD. Now that Catalina GM Build is live, we should be very close to the public release of 10.15.

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 10 and the new Catalina 10.15 GM Seed #1 (19A582a) release notes to find all the changes. When Apple releases the next Beta patch notes, the previous patch notes are overwritten and taken down.

10.15 GM Seed #1 or Beta 11 ?

NOTE: I am calling this GM Seed #1 because it’s my bet that we will see a GM Seed #2. The evidence is that Apple is still calling this release.

Install macOS Catalina Beta.app

I don’t know for sure though. Apple could just release the current build and change the name!!!

I for one really hope this is the case, as we still have some things that need to be addressed before launch.

1 New Features

Report your bugs NOW!

This may be the final beta left to test. The public Release of Catalina is only a week or two away! 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 Octobers’s release date. If you wait it could be months before the fix is put into a dot release combo update.

AppleSeed Patch Notes & Some Fixes not listed?

Some fixes are not going to be listed. Many issues are from #MacAdmins who have filed FeedBack Requests and Enterprise Support tickets. Most of these issues are resolved but are never publicly noted.

1. New Features in Beta 9

iCloud – Launch daemons and launch agents introduce new user privacy protections. Specifying privacy-sensitive files and folders in a launchd property list might not work as expected and prevent the service from running. Having Program or ProgramArguments pointing to an executable in a privacy sensitive location is currently allowed, but may be restricted in a future release. (49702405)To comply with the new privacy protections, resources for a launchd service must be stored in locations that aren’t privacy sensitive. If necessary, the app can set up resources during its execution rather than using launchd property list keys, making it possible to grant the app access using System Preferences > Security & Privacy > Privacy. The following launchd property list keys are affected: KeepAlive, PathState, QueueDirectories, Sockets, SockPathName, StandardErrorPath, StandardInPath, StandardOutPath, and WatchPaths.

2. New Resolved issues

Localization – Fixed an issue where certain languages might exhibit clipped or misaligned layout. (51068688, 50983852)

Localization – Fixed an issue where certain languages might display unlocalized text. (47765173, 51196633)

3. New Known Issues

Mac Catalyst – DOM keyboard events aren’t dispatched as expected in WKWebView when pressing or releasing keys. Web apps needing to track typed characters can instead listen for DOM input events. (54580414)

Remote Desktop – Turning on Curtain Mode prevents you from being able to control a remote Mac. (52900397)

AppleSeed Patch Notes & Some Fixes not listed?

Some fixes are not going to be listed. Many issues are from #MacAdmins who have filed FeedBack Requests and Enterprise Support tickets. Most of these issues are resolved but are never publicly noted.

1. New Features in Beta 8

SwiftUI – NSManagedObject now conforms to ObservableObject. The new @FetchRequest property wrapper can drive views from the results of a fetch request, and managedObjectContext is now included in the environment. (50280673)

SwiftUI – BindableObject is replaced by the ObservableObject protocol from the Combine framework. (50800624)You can manually conform to ObservableObject by defining an objectWillChange publisher that emits before the object changes. However, by default, ObservableObject automatically synthesizes objectWillChange and emits before any @Published properties change.// RoomStore.swift import Foundation class RoomStore: ObservableObject { @Published var rooms: [Room] = [] } struct Room: Identifiable { var id: UUID var name: String var capacity: Int var hasVideo: Bool } // ContentView.swift import SwiftUI struct ContentView: View { @ObservedObject var store: RoomStore var body: some View { NavigationView { List(store.rooms) { room in RoomCell(room: room) } .navigationBarTitle(“Rooms”) } } } @ObjectBinding is replaced by @ObservedObject.

SwiftUI – The RangeReplaceableCollection protocol is extended to include a remove(atOffsets:) method and the MutableCollection protocol is extended to include a move(fromOffsets:toOffset:) method. Each new method takes IndexSet instances that you use with the onMove(perform:) and onDelete(perform:) modifiers on ForEach views. (51991601)

2. New Resolved Issues in Beta 8

Apple TV – Support for signing in with an account from a different country is now available. (51240948)

iWork – Attempting to open iWork documents in Finder will no longer unexpectedly create a .cpgz file if the corresponding iWork app isn’t installed. (40693892)

Mac Catalyst – Fixed an issue where event handling in extension contexts sometimes produced unexpected results, including failure to deliver trackpad pinch and zoom gestures. (50145462)

3. New Known Issues in Beta 8

Mac Catalyst – Catalyst apps using UIDocumentInteractionController might quit unexpectedly. You can work around this issue by excluding UIDocumentInteractionController functionality with target macros. (48878552)

SwiftUI – Apps containing SwiftUI inside a Swift package might not run on versions of iOS earlier than iOS 13. (53706729)Workaround: When back-deploying to an OS which doesn’t contain the SwiftUI framework, add the -weak_framework SwiftUI flag to the Other Linker Flags setting in the Build Settings tab. See Frameworks and Weak Linking for more information on weak linking a framework. This workaround doesn’t apply when using dynamically linked Swift packages which import SwiftUI.

4. New Deprecations in Beta 8

EndpointSecurity – (Left over from last time as it was incorrectly noted that this was removed) The kauth API has been deprecated. (50419013)

SwiftUI – Complex overloads for the background(:alignment:) and border(:width:) modifiers are deprecated. Use shapes in a background(:alignment:) or overlay(:alignment:) to draw these instead. (53067530)

SwiftUI – The identified(by:) method on the Collection protocol is deprecated in favor of dedicated init(:id:selection:rowContent:) and init(:id:content:) initializers. (52976883, 52029393)The retroactive conformance of Int to the Identifiable protocol is removed. Change any code that relies on this conformance to pass .self to the id parameter of the relevant initializer. Constant ranges of Int continue to be accepted:List(0..<5) { Text(“Rooms”) } However, you shouldn’t pass a range that changes at runtime. If you use a variable that changes at runtime to define the range, the list displays views according to the initial range and ignores any subsequent updates to the range.

SwiftUI – Several extensions to the Binding structure are removed. (51624798)If you have code such as the following:struct LandmarkList: View { var landmark: [Landmark] @Binding var favorites: Set var body: some View { List(landmarks) { landmark in Toggle(landmark.name, isOn: self.$favorites.contains(landmarkID)) } } } Define the following subscript on the Set structure:extension Set { subscript(member: Element) -> Bool { get { contains(member) } set { if newValue { insert(member) } else { remove(member) } } } } Then, change self.$favorites.contains(landmarkID) to self.$favorites[landmarkID].

Xcode 11 GM Seed 2 Patch Notes Changes

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)
