I built an app that makes playing audio plays easier using MusicKit. Now I am about to release the app to the app store. Following questions occured while doing so: Am I accessing/showing third party content in my app when I am music (in this case radio plays) from MusicKit? I am getting all of that data directly from Apple. Is Apple a third party in this case? The publisher has an app that can playback all of the content that can be accessed in my app. This app has an age rating of 4+ years. Can I just copy that? I've heard that referring to other apps doesn't convince the App Review Team if they disagree. None of the titles are marked explicit in Apple Music. Under the hood MusicKit is using HTTPS to get the data from Apple's servers. I have no code that has anything to do with encryption or HTTPS. Does my app still uses Non Exempt Encryption because MusicKit does so? Can I access music through MusicKit that is otherwise not available in this region or does MusicKit take care of this for me? In other words do I have to restrict the availability of my app to certain regions so I don't bypass any geo blockings by accident? Thank you

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 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

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

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 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

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 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
