I am seeing a really weird behavior with Live Activities. The Live Activity is always appearing on the simulator. However the Live Activity is only appearing on my physical device when there is no other widget in the widget bundle shown below. @main struct HoerspielWidgetsBundle: WidgetBundle { var body: some Widget { // Uncomment the line below and the Live Activity will no longer appear // UpNextWidget() PlaybackLiveActivity() } } Annotating that var with @WidgetBundle has no effect. There are no logs indicating an error, the function to request a Live Activity does not throw and the status of the activity is active. Both the widget and the Live Activity are working fine otherwise. NSSupportsLiveActivities is set to true in the correct Info.plist file. I am not running any beta software and the physical iPhone is on the newest version (iOS 18.5). Using the template when adding a new target in Xcode, I was able to set up a similar app where the Live Activity works as expected. I am really at a loss here which additional information I should provide or how this issue can be resolved. Thank you for your help.

I want to load images from my bundle, which works fine when running the main app. However this does not work when running UI Tests. I read that the test bundle is not the main bundle when running tests. I try loading the bundle via this snippet: let bundle = Bundle(for: Frames_HoerspielUITests.self) This is my test class wrapped these the canImport statements so it can be added to the main app target and used for getting the correct bundle: #if canImport(XCTest) import XCTest final class Frames_HoerspielUITests: XCTestCase { override func setUpWithError() throws { continueAfterFailure = false } override func tearDownWithError() throws { } @MainActor func testExample() throws { let app = XCUIApplication() app.launch() } @MainActor func testLaunchPerformance() throws { measure(metrics: [XCTApplicationLaunchMetric()]) { XCUIApplication().launch() } } } #else final class Frames_HoerspielUITests { } #endif However while this works when running the main app, it still fails in the UI tests. It is a SwiftUI only app. and I can't add the images to the asset catalog because they are referenced from another location. Any ideas? Thank you

I use Universal Product Codes (UPC) in my app to reliably identify albums after having used albumIDs for a time. AlbumIDs can change over time for no obvious reasons (see here for songIDs) so I switched to UPCs since I believed they cannot change. Well apparently they can. A few days ago I populated a JSON with UPCs including 196871067713. Today trying to perform a MusicCatalogResourchRequest for the UPC does not return anything. When using that UPC and putting it into an Apple Music link like https://music.apple.com/de/album/folge-89-im-geistergarten/1683337782?l=en-GB redirects to https://music.apple.com/de/album/folge-89-im-geistergarten/1683337782?l=en-GB so I assume the UPC has changed from 196871067713 to 1683337782. Apple Music can handle that and redirects to the new upc both in the app and as a website. But a MusicCatalogResourceRequest cannot do that. I filed a suggestion for that (FB15167146) but I need a solution quicker. Can I somehow detect where the URL is redirecting to? Is there a way MusicCatalogResourceRequest can do this? Performing a MusicCatalogSearchRequest can be an option but seems unreliable when using the title as search term. Other ideas? Thank you

The following complex migration consistently crashes the app with the following error: SwiftData/PersistentModel.swift:726: Fatal error: What kind of backing data is this? SwiftData._KKMDBackingData<SwiftDataMigration.ItemSchemaV1.ItemList> My app relies on a complex migration that involves these optional 1 to n relationships. Theoretically I could not assign the relationships in the willMigrate block but afterwards I am not able to tell which list and items belonged together. Steps to reproduce: Run project Change typealias CurrentSchema to ItemSchemaV2 instead of ItemSchemaV1. Run project again -> App crashes My setup: Xcode Version 16.2 (16C5032a) MacOS Sequoia 15.4 iPhone 12 with 18.3.2 (22D82) Am I doing something wrong or did I stumble upon a bug? I have a demo Xcode project ready but I could not upload it here so I put the code below.

Hi, is there a way to display the animated cover art in an app? Not every album has a cover art but for the ones that have one I would like to display them instead of the artwork. Thank you :)

Apparently the @Query property wrapper from SwiftData does not update when data is loaded from CloudKit. The data can be programmatically be accessed but nothing appears in the view. Steps to reproduce: Create new Xcode project using the SwiftData storage option. Provide a default value for the Item Model. That is required so data can be automatically synced by SwiftData. Enable iCloud -> CloudKit capabilities and choose a container Enable Background Modes -> Remote notification capability Add a toolbar button that prints the number of items from @Query like this: ToolbarItem { Button { print(items.count) } label: { Label("Count", systemImage: "1.circle") } } Install app on a physical device that can sync to iCloud. Add some items using the + in the toolbar Delete app and wait for around a minute Reinstall app with a debugger attached Press the 1.circle button in the toolbar. It will print either 0 or the number of items you previously added. When it does not print 0 the data should be visible but it is not. Once you quit and relaunch the app or press the + button again, all of the items appear. Has anyone else experienced this before? Anything I can do so the data appears / the view reloads once the items are available? I need to update my view once the data has been loaded from iCloud. I already filed a bug report with id FB14619787.

I am trying to bring my iOS App to native macOS. I am using exactly the same TimelineProvider and widgets (the ones not supported on macOS surrounded by #if(os)). Running the whole app or just the WidgetExtension on iOS works perfectly fine. Running the mac app works perfectly fine apart from missing Widgets. When running the WidgetExtension on My Mac, the WidgetKit Simulator opens and only presents Failed to load widget. The operation couldn't be completed. (WidgetKit_Simulator.WidgetDocument.Error error 4.) The code compiles fine without any warnings, only a file path is printed into the console. file:///Users/myName/Library/Developer/Xcode/DerivedData/MyAppName-dfsiuexplidieybwvbkqofchxirp/Build/Products/Debug/MyApp.app/Contents/PlugIns/MyAppNameWidgetExtensionExtension.appex/ Shortly after I get a log entry Logging Error: Failed to initialize logging system. Log messages may be missing. If this issue persists, try setting IDEPreferLogStreaming=YES in the active scheme actions environment variables. I am not sure which further Informationen I can give to solve my problem. Destinations on main App and Widget Extension is both set to Mac (no suffix). The mac is running 14.4.1 and Xcode 15.3. I am really thankful for any assistance you can give me to fix this problem. Thanks

Is there a way to display a .icon file in SwiftUI? I want to show the app icon in the app itself but exporting and including the app icon as a PNG feels redundant. This would consume a lot of unnecessary storage especially when including a lot of alternative app icons. There has to be a better way Otherwise I would file a feedback for that Thank you
