Symbol not found: NSUserActivityTypeLiveActivity and WidgetCenter.UserInfoKey.activityID
The app I'm working on has iOS 16.0 as target. Recently Live Activities support was added, but then it started crashing when running on iOS 16.0 devices. After some investigation, I've found that the culprit was the presence of NSUserActivityTypeLiveActivity and WidgetCenter.UserInfoKey.activityID, even though they were inside an @available(iOS 17.2, *) block. If I comment these two variables, the app work as expected. I've also tried adding #if canImport(ActivityKit) around the code, but without success. But if the @available isn't working, how can I prevent this? It looks like a bug, since the documentation says that NSUserActivityTypeLiveActivity is supported but iOS 14.0+, but I'm pretty sure it was introduced on 16.1. This is the only output I get with the crash: dyld[66888]: Symbol not found: _$s9WidgetKit0A6CenterC11UserInfoKeyV10activityIDSSvgZ Referenced from: <D6EFF120-2681-34C1-B261-8F3F7B388238> /Users/<redacted>/Library/Developer/CoreSimulator/Devices/8B5B4DC9-3D54-4C91-8C88-E705E851CA0F/data/Containers/Bundle/Application/DB6671FF-CB07-4570-BD63-C851D94FAF29/<redacted>.app/<redacted>.debug.dylib Expected in: <C5E72BB5-533F-3658-A987-E849888F4DFC> /Library/Developer/CoreSimulator/Volumes/iOS_20A360/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 16.0.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/WidgetKit.framework/WidgetKit

UI Test Cases Failing with Custom Accessibility Labels in SwiftUI
Hello Apple Developer Support, I am writing to seek assistance with an issue we are experiencing in our SwiftUI application concerning UI test cases. Our application uses accessibility labels that differ slightly from the display content to enhance VoiceOver support. However, we have encountered a problem where our UI test cases fail when the accessibility label does not match the actual display content. Currently, we are using accessibility identifiers in our tests, but they only retrieve the accessibility label, leaving us without a method to access the actual display content. This discrepancy is causing our automated tests to fail, as they cannot verify the visual content of the UI elements. We would greatly appreciate any guidance or solutions you could provide to address this issue. Specifically, we are looking for a way to ensure our UI tests can access both the accessibility label and the actual display content for verification purposes. For ex: Problem scenario - setting accessibilityLabel masks access to any displayed content If an accessibilityLabel is set on a UI element, then it seems to be no-longer possible to check/access the displayed content of that element: var body: some View { Text("AAA") .accessibilityIdentifier("textThing") .accessibilityLabel("ZZZ") // Different label from the text which is displayed in UI } // in test... func test_ThingExists() { XCTAssert(app.staticTexts["AAA"].exists) // Fails, cannot find the element XCTAssertEqual(app.staticTexts["ZZZ"].label, "AAA") // Fails - '.label' is the accessibilityLabel, not the displayed content XCTAssertEqual(app.staticTexts["ZZZ"].label, "ZZZ") // Passes, but validates the accessibility content, not the displayed content XCTAssert(app.staticTexts["textThing"].exists) // Passes, but does not check the displayed content XCTAssertEqual(app.staticTexts["textThing"].label, "AAA") // Fails - '.label' is the accessibilityLabel, not the displayed content XCTAssertEqual(app.staticTexts["textThing"].label, "ZZZ") // Passes, but validates the accessibility content, not the displayed content } element.label still only checks the accessibilityLabel. There is not, it seems, an way back to being able to check the content of the Text element directly. Thank you for your attention and support. We look forward to your valuable insights.

iOS 18.3.1 - runtime vs version number
Not sure if this is common with releases but I've been doing some CI work recently so it's the first time I've seen this myself, When I list the runtimes installed on my machine: xcrun simctl list runtimes I notice the iOS 18.3.1 release has the below info: == Runtimes == iOS 18.3 (18.3.1 - 22D8075) - com.apple.CoreSimulator.SimRuntime.iOS-18-3 Meanwhile the other runtimes are listed as: == Runtimes == iOS 17.5 (17.5 - 21F79) - com.apple.CoreSimulator.SimRuntime.iOS-17-5 iOS 18.4 (18.4 - 22E5216h) - com.apple.CoreSimulator.SimRuntime.iOS-18-4 watchOS 11.2 (11.2 - 22S99) - com.apple.CoreSimulator.SimRuntime.watchOS-11-2 visionOS 2.3 (2.3 - 22N895) - com.apple.CoreSimulator.SimRuntime.xrOS-2-3 (Apologies for the weird formatting above, using code blocks and quote markdown condenses things down to one line for some reason) This is causing some funkiness in my CI code which I've managed to workaround, but wondered if this was a common thing, specifically the mismatch between the iOS name and the runtime version. iOS 18.3 and com.apple.CoreSimulator.SimRuntime.iOS-18-3 vs 18.3.1 - 22D8075 where the .1 has been dropped for the runtime names?

Discrepancies in MetricKit and Xcode Organizer Data
We recently integrated MetricKit into our app; however, the 90th percentile data does not seem to match the data in Xcode Organizer. The values reported by MetricKit appear to be higher. Additionally, it looks like data for previous app versions is not being updated in Organizer as adoption of the latest version increases. Has anyone else experienced this issue? Could there be a delay in data updates for older versions in Organizer? Are there any known limitations or best practices for ensuring consistency between MetricKit and Xcode Organizer data? Any guidance would be greatly appreciated.

Why does my zsh prompt permanently change?
Hey, I am using the terminal a lot. Since I updated to Sonoma (so, really a long time ago). My prompt or more precise the hostname always changes between three states. Sometimes it is username@Macbook-Pro-of-XXX, sometimes username@MacbookPro and sometimes it's username@xxxxxxxx-yyyy-zzzz-aaaa-bbbbbbbbbbbb. The latter is probably my UUID. Does anyone have a clue why this randomly changes?

The Xcode project keeps crashing on launch
Hello, I need a little bit of help. My game keeps crashing on launch no matter what I do. I’ve tried running it in Xcode on my Mac, on my iPhone, and through TestFlight, but I get the same result every time. I’ve tried everything I could find on the internet, and nothing worked. Asking here is my last resort because I’m completely stuck. The game runs fine in Unity, but not so much in Xcode. Can someone help me figure out what I’m doing wrong?Any help would be greatly appreciated. Here is the error log I found by connecting my iPhone to my Mac. To view the logs, I used the Console in the Devices and Simulators section of Xcode. ➤ SecKeyVerifySignature failed: Error Domain=NSOSStatusErrorDomain Code=-50 "rsa_pub_crypt failed" [10:27:36.034791+0200] kernel ➤ Sandbox: [App] deny(1) sysctl-read kern.bootargs [10:27:36.043389+0200] SpringBoard ➤ Live host view super view[(null)] not matching container view ➤ Frame not updated [10:27:36.050473+0200] backboardd ➤ Cycle detected [10:27:36.100799+0200] SpringBoard ➤ Live host view super view[(null)] not matching container view [10:27:36.538361+0200] akd ➤ Error fetching keychain item - Error Domain=NSOSStatusErrorDomain Code=-25300 "no matching items found" [10:27:36.545734+0200] akd ➤ Failed to set last known MID with error (Error Domain=NSOSStatusErrorDomain Code=-25300) [10:27:36.603384+0200] rtcreportingd ➤ Gap in hierarchy: [10:27:36.604536+0200] cloudd ➤ TCP input flags=[R.] state=LAST_ACK [10:27:36.613317+0200] cloudd ➤ TCP input flags=[R] state=CLOSED [10:27:36.648449+0200] kernel ➤ 1 duplicate report for Sandbox: [App] deny(1) sysctl-read kern.bootargs [10:27:36.648484+0200] kernel ➤ Sandbox: [App] deny(1) file-test-existence /private/var/Managed Preferences/mobile/com.apple.CoreMotion.plist [10:27:36.900275+0200] CommCenter ➤ Client is not entitled for request [10:27:37.131555+0200] storekitd ➤ AMSURLSession: Session decoder failed.

Apollo GraphQL Error – MultipartResponseParsingInterceptor.ParsingError.cannotParseResponse in SwiftUI
I'm integrating Apollo GraphQL into a SwiftUI app and encountering the following error during a query execution: result : failure(Apollo.MultipartResponseParsingInterceptor.ParsingError.cannotParseResponse) failed : The response data could not be parsed. The request hits the server, but the response fails to be parsed by Apollo. I'm using the default code generation setup and executing a simple query to fetch a list of countries. Here’s a snippet of the function: swift Copy Edit private func fetchCountries() { switch result { case .success(let graphQLResult): if let name = graphQLResult.data?.countries { print(name) } else if let errors = graphQLResult.errors { print(errors) } case .failure(let error): print("failed : (error.localizedDescription)") } } This is run on an iPhone 16 Pro simulator with iOS 18.2. Any idea what's causing the parsing error or how I can inspect the raw response for debugging? Thanks in advance!

Are watchdog timeout terminations a crash or not?
If an iOS app gets terminated by watchdog due to, for example, hanging the main thread, is that considered to be a crash or something different. I'm asking because, according to google and AI, Crashlytics can detect and report these,but in my experience it does not. If I deliberately cause a watchdog termination by for example sleeping on the main thread for a long time then these never appear in Crashlytics. I know Apple folks here don't comment on non Apple software, so I'm not asking about Crashlytics, just wondering and interested about watchdog timeout terminations and how they differ from a "regular" crash.

Interpreting crash log assertionFailure
Hello, I am experiencing crash on TopShelf and I checked all the crashlogs, but I don't know how to interpret it. I see only addresses in the trace logs, so it's really hard to understand what's going on. Is there a way how to symbolicate frames 5 - 17? Does anybody have an idea, what can be wrong?

Need guidance for creating the xcprivacy file WITHOUT A MAC when coding on flutter, especially when third party sdks are there.
When you have a mac, creating xcprivacy is pretty straightforward for your app, you simply use xcode, then select the sdks and target them and your privacy manifest is ready. In the other hand, when you are using CI/CD solutions you might not use xcode direclty. In that instance and if you are coding in flutter, you need to create your privacy manifest by hand. I would like guidance how to write that file, I would it for a given third party SDK and where to put that file in the flutter project (just to be sure) For example we choose the most important third party SDK manifest: FUTTER framework. I keep getting errors about it for my app, got alot of builds get the INVALID BINARY error because of that, and my mails indicating me a problem with the manifest. Please show me the source code of the manifest privacy for a project where a third party SDK is present (in particular: flutter sdk) Thanks

NSUserDefaults + iPhone Transfer Issues
Hi! I was wondering if anyone else encountered similar issues and what the solution ended up being. We're encountering weird sign-in issues on our iOS version of our app. It seems like an uninstall and reinstall solves it, but the issue seems to only impact users who underwent the transfer process from one iOS device to another. What I am curious about: What is copied over from one device to another in this process? Is there a way outside of owning multiple test devices to replicate this flow? Our current suspicion is that NSUserDefaults is not being cleared by our app on first start, and that stale data is copied over during this transfer process, breaking the sign-in until a re-install wipes everything properly. Does it seem like we're on the right track with this assumption, or completely out to lunch?

MacOS 15.4 removes rsync —log-file option?
I installed MacOS Sequoia 15.4 and now my backup script no longer works. My script is using rsync in this way: rsync -avz —delete —log-file=“$LOG_FILE” “$SRC_DIR” “$DEST_DIR” This has been working fine for a very long time. After updating to 15.4, this produces the error “rsync: unrecognized action —log-file=/users/admin/logs/backuplog_xxx.log”. The log file path is correct (and hasn’t changed). Interestingly, the man page for rsync no longer shows the —log-file as an option. I know I can use: rsync -avz —delete “$SRC_DIR” “$DEST_DIR” > “$LOG_FILE”` or even rsync -avz —delete “$SRC_DIR” “$DEST_DIR” > “$LOG_FILE” 2>&1` to also capture stderr. However, I liked the output from the built-In log option. Does anyone know why this might have been removed or if there is a way to get it back? Thanks.

Workbench Ad Tester not returning preview URLs
Apologies if this isn't tagged right but dev tools and services seemed the most appropriate since this is related to the workbench Ad Tester tool. I'm seeing a behavior where the preview link is not being generated. Specifically, I am seeing a POST request to the following URL consistently fail: https://iadworkbench.apple.com/adtester/api/v1/ads/previewLink?orgId=1127861 Variations/scenarios I have tried so far: All possible ad format choices on all possible devices All options for the placement type Both third party and uploaded creative sources Uploaded creative sources appear to be failing to upload as well A simple div with a "hello world" content fails as a third party creative source Multiple apple accounts I created a new account specifically to test if my primary apple ID was experiencing issues with this Multiple browsers I have tried multiple versions of Chrome/Firefox/Safari I tested with and without browser extensions to determine whether an extension was interfering or not Clearing session/local storage along with cookies I also created new profiles in browsers to verify that I was getting a fresh browser environment In all of these cases, the API request to generate a preview link is consistently failing with a 500 error code. It's worth noting that the web preview option works, but this isn't a truly accurate test environment and can't be solely relied on when testing ad content. I don't know exactly when this started happening as I have not used it in the last couple of weeks but I have used the workbench ad tester extensively in the past the same way I have been trying with my current test without issue. That coupled with the fact that the request for the preview link consistently fails in all of the test scenarios I've outlined above leads me to believe there is a problem with the API that is responsible for generating the preview links.

PDF opening from iOS Unity app in landscape mode instead of portrait
In our Unity App for iOS build, when we opened the PDF from the app, it is automatically opening in landspace mode instead of portrait. In the android and windows apps, we are able to open in the portrait mode. We tried to make the changes in the project settings but it did not change. Any way in which we can acheive this would be helpful for us.
