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

I am trying to integrate fastlane, which relies on xcodebuild. So this is my first experience with xcodebuild. Whenever I run a command to test or build the target in the folder where all the files of the project are stored, the action failes with Unable to find a device matching the provided destination specifier For example I might be running this command: xcodebuild \ -project Hoerspielzentrale.xcodeproj \ -scheme HoerspielzentraleUITests \ -destination 'platform=iOS Simulator,name="Screenshot Simulator”' \ test However the mentioned error is returned: xcodebuild: error: Unable to find a device matching the provided destination specifier: { platform:iOS Simulator, OS:latest, name:"Screenshot Simulator” } The requested device could not be found because no available devices matched the request. I can confirm that the simulator exists, is available and it can be booted. I have tried different simulators, different schemas, referencing them by their identifier, switching Xcode Versions, reset all simulators, derived data and build folder. After the error a complete list of all available destinations can be found, where I can see the simulator I try to use. Available destinations for the "HoerspielzentraleUITests" scheme: { platform:iOS, id:dvtdevice-DVTiPhonePlaceholder-iphoneos:placeholder, name:Any iOS Device } { platform:iOS Simulator, id:dvtdevice-DVTiOSDeviceSimulatorPlaceholder-iphonesimulator:placeholder, name:Any iOS Simulator Device } { platform:iOS Simulator, id:961DC569-9931-419A-B46E-769AAFA73EA2, OS:18.5, name:Screenshot Simulator } { platform:iOS Simulator, id:961DC569-9931-419A-B46E-769AAFA73EA2, OS:18.5, name:Screenshot Simulator } { platform:iOS Simulator, id:5E51FD98-C451-472F-9CDE-08D49E6B737B, OS:18.5, name:Screenshot Simulator Pro } { platform:iOS Simulator, id:5E51FD98-C451-472F-9CDE-08D49E6B737B, OS:18.5, name:Screenshot Simulator Pro } The rest of the list was omitted. I am currently completely stuck. Thank you

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

ApplicationMusicPlayer is not available on watchOS but all other platforms. Is there a technical reason for that like battery life? Same goes for SystemMusicPlayer and MPMusicPlayerController. I already filed feedbacks for that.

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.

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.

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 prefer to use the album fetched from the library instead of the catalog since this is faster. If doing so, how can I check if all tracks of an album are added to the library. In this case I'd like to fetch the catalog version or throw an error (for example when offline). Using .with(.tracks) on the library album fetches the tracks added to the library. The trackCount property is referring to the tracks that can be fetched from the library. The isComplete property is always nil when fetching from the library. One possible way is checking the trackNumber and discCount properties. However this only detects that not all tracks of an album are added to the library if there is a song not added ahead of one that is. I'd like to be able to handle this edge case as well. Is there currently a way to do this? I'd prefer to not rely on the apple music catalog for this since this is supposed to work offline as well. Fetching and storing all trackIDs when connected and later comparing against these would work, but this would potentially mean storing tens of thousands of track ids. Thank you

When using the old withTaskCancellationHandler(operation:onCancel:isolation:) to run background tasks, you were notified that the background task gets cancelled via the handler being called. SwiftUI provides the backgroundTask(_:action:) modifier which looks quite handy. However how can I check if the background task will be cancelled to avoid being terminated by the system? I have tried to check that via Task.isCancelled but this always returns false no matter what. Is this not possible when using the modifier in which case I should file a bug report? Thanks for your help

I am experimenting with Swift Testing and Xcode Cloud and would like to write some tests that require to use MusicKit functionality. For example I'd like to fetch an album via MusicCatalogRessourceRequest to test an initializer of another struct. However this test fails because the permission to access the music library is not granted. Once the permission is granted, the test works as expected. Things I have tried: Add NSPrivacyAccessedAPITypes to the Info.plist. This did not show any effect. Below is the corresponding snippet Trying to tap the button programmatically. Once again this did not show any effect. The Info.plist snippet: <key>NSPrivacyAccessedAPITypes</key> <array> <string>NSPrivacyAccessedAPIMediaLibrary</string> </array> The code snippet to tap the button: let systemAlerts = XCUIApplication(bundleIdentifier: "com.apple.springboard") let allowButton = systemAlerts.buttons["Allow"] if allowButton.exists { allowButton.tap() } What am I doing wrong here? I need access to MusicKit functionalities to write meaningful tests. Thank you

Songs can be unavailable (greyed out) in Apple Music. How can I check if a song is unavailable via the MusicKit framework? Obviously the playback will fail with MPMusicPlayerControllerErrorDomain Code=6 "Failed to prepare to play" but how can I know that in advance? I need to check the availability of hundreds of albums and therefore initiating a playback for each of them is not an option. Things I have tried: Checking if the release date property is set to a future date. This filters out all future releases but doesn't solve the problem for already released songs. Checking if the duration is 0. This does not work since the duration of unavailable songs does not have to be 0. Initiating a playback and checking for the "Failed to prepare to play" error. This is not suitable for a huge amount of Albums. I couldn't find a solution yet but somehow other third-party-apps are able ignore/don't shows these albums. I believe the Apple Music app is only displaying albums where at least one song is available. I am using this function to fetch all albums of an artist. private func fetchAlbumsFor(_ artist: Artist) async throws -> [Album] { let artistWithAlbums = try await artist.with(.albums) var allAlbums = [Album]() guard var currentBadge = artistWithAlbums.albums else { return [] } allAlbums.append(contentsOf: currentBadge) while currentBadge.hasNextBatch { if let nextBatch = try await currentBadge.nextBatch() { currentBadge = nextBatch allAlbums.append(contentsOf: nextBatch) } else { break } } return allAlbums } Here is an example album where I am unable to detect its unavailability (at least in Germany): https://music.apple.com/de/album/die-haferhorde-immer-den-n%C3%BCstern-nach-h%C3%B6rspiel-zu-band-3/1755774804 Furthermore I was unable to navigate to this album via the Apple Music app directly. Thanks for any help Edit: Apparently this album is not included in an apple music subscription but can be bought seperately. The question remains: How can I check that?

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 :)

I am having trouble accessing the lastPlayedData for any given album or track using MusicKit. The value is always nil, both on numerous albums and tracks I tested. Afaik this is not a property that has to be fetched separately like tracks for example. I am running this on my physical iPhone 12 18.1.1 with Xcode 16.1. The albums and tracks have definitely been played multiple times before. The app has permission to the library using MusicAuthorization.request() This post mentions the same problem but offers no solution. Thanks for any help

Can I use the TestFight app icon to link to my app inside TestFlight? All I found is this forum post that does not give a precise answer. Should I contact https://www.apple.com/legal/contact/trademark-information.html for that matter? 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

I want to switch from using print statements to using OSLog because of the filtering options and so on. I am using MusicKit. To mute all the log noise mostly coming from CoreData I pass these arguments on launch: -com.apple.CoreData.SQLDebug 0 -com.apple.CoreData.MigrationDebug 0 -com.apple.CoreData.ConcurrencyDebug 0 -com.apple.CoreData.CloudKitDebug 0 -com.apple.CoreData.Logging.stderr 0 This works for all the Core Data related warnings but I also need such an argument for MusicKit. Setting the environment variable OS_ACTIVITY_MODE to disable hides all the noise but also hides the log statements I sent via Logger().debug() for example. In particular these log messages appear in great quantities. Attempted to register account monitor for types client is not authorized to access: {( "com.apple.account.iTunesStore" )} <ICMonitoredAccountStore: 0x303c5c9f0> Failed to register for account monitoring. err=Error Domain=com.apple.accounts Code=7 "(null)" My application works fine and these log messages mean absolutely nothing to me. These two threads mention a similar problem but can't offer a solution. https://forums.developer.apple.com/forums/thread/720835 https://forums.developer.apple.com/forums/thread/743795 Thank you
