I filed FB13689023 for this since it is clearly unexpected. Non Apple Music library tracks are not returned on macOS using MusicLibraryRequest. I tried querying by artist where I only get Apple Music tracks, and by id where I don't get the track. On iPhone and iPad I was able to get both AM and non-AM tracks, that's how I got a valid id to try on macOS. Sync Library is on. The build targets My Mac (Designed for iPad). I'm using Xcode 15.3 and I'm on Sonoma (14.4). Any help is appreciated...

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

Hi there, I have a related forum thread here and a Feedback Assistant ticket open, but this issue seems different. Sometime within the last 2-3 weeks, code related to MusicLibrary has stopped working. None of my code has changed. For example, the below two snippets used to work fine:  for track in newTracks {    try await MusicLibrary.shared.add(track, to: targetPlaylist)  } try await MusicLibrary.shared.edit(targetPlaylist, items: items) newTracks and items are both fetched using: try await targetPlaylist.with(.tracks, preferredSource: .catalog).tracks Using preferredSource: .catalog was a workaround used to address the issue in the aforementioned post above. All iOS 16 capable functions are decorated with: @available(iOS 16, *) or in an if block: if #available(iOS 16, *) {... What's happening is that the following is showing up in the console: 2022-11-28 23:31:11.279648+0700 MyApp[38653:6736450] [core] Attempted to register account monitor for types client is not authorized to access: {(     "com.apple.account.iTunesStore" )} 2022-11-28 23:31:11.279718+0700 MyApp[38653:6736450] [Default] <ICUserIdentityStoreACAccountBackend: 0x282adb520> Failed to register for account monitoring. err=Error Domain=com.apple.accounts Code=7 "(null)" 2022-11-28 23:31:11.279758+0700 MyApp[38653:6736450] [Default] ICUserIdentity - Unable to retrieve DSID for userIdentity=<ICUserIdentity 0x2806eb120: [Active Account: <unresolved>]> - error=Error Domain=com.apple.accounts Code=7 "(null)" These errors are not caught by a do/catch block, but I assume they are related to the issue, and I believe they have to do with MyApp trying to access things that Music Kit thinks it's not supposed to. For example, if MyApp attempts to work with a playlist that it did not create, errors would be expected, thrown errors. The thing is that I know I'm working with resources that are created by MyApp. In fact, in trying to test this, I just tried to create a playlist with the below, and the same behavior is occurring: @available(iOS 16, *) func createPlaylist2(name: String, description: String) async -> MusicKit.Playlist? {     do {         Logger.log(.info, "Creating Playlist: \(name)")         Logger.log(.shrug, "Does this work?")         let newPlaylist = try await MusicLibrary.shared.createPlaylist(name: name, description: description) // <= Things stop here!         Logger.log(.success, "New playlist created: \(newPlaylist)") // <= this isn't logged.         return newPlaylist // <= nothing is returned     } catch {         Logger.log(.error, "Could not create new playlist: \(error)") // <= no error logged.     }     return nil } The result is: 2022-11-29 00:15:01.875064+0700 MyApp[38794:6760471] [core] Attempted to register account monitor for types client is not authorized to access: {(     "com.apple.account.iTunesStore" )} 2022-11-29 00:15:01.875372+0700 MyApp[38794:6760471] [Default] <ICUserIdentityStoreACAccountBackend: 0x283005720> Failed to register for account monitoring. err=Error Domain=com.apple.accounts Code=7 "(null)" 2022-11-29 00:15:01.876677+0700 MyApp[38794:6760323] [EntityQuery] Finished executing query in 0.000999928s 2022-11-29 00:15:01.889055+0700 MyApp[38794:6760323] [EntityQuery] Finished fetching results in 0.0120001s 2022-11-29 00:15:01.891235+0700 MyApp[38794:6760329] [core] Attempted to register account monitor for types client is not authorized to access: {(     "com.apple.account.iTunesStore" )} 2022-11-29 00:15:01.891684+0700 MyApp[38794:6760329] [Default] <ICUserIdentityStoreACAccountBackend: 0x283005720> Failed to register for account monitoring. err=Error Domain=com.apple.accounts Code=7 "(null)" 📘 Creating Playlist: TEST PLAYLIST 🤷🏻‍♀️ Does this work? 2022-11-29 00:15:06.697374+0700 MyApp[38794:6760329] [] nw_path_necp_check_for_updates Failed to copy updated result (22) What's really nasty is that errors are not thrown, so they can't be caught and handled in a catch block.

Any help would be most appreciated. @JoeKhun: Did I miss the memo?

Is there a way to get the current queue items from an MPMusicPlayerController? I need to know when the items I've set to the queue finish playing completely but cannot find any way to do this. I am not using MusicKit but setting the queue via play parameters. From what I can tell so far, after the queue finishes playing, it pauses and resets to the first item in the queue. So even after playback is done, there is no way to know that it finished on its own.

I'm using the systemMusicPlayer to play music and want to update the playback time using addObserver forKeyPath. [self setMusicPlayer: [MPMusicPlayerController systemMusicPlayer]]; I've tried these two methods: [self addObserver:self forKeyPath:@"musicPlayer.currentPlaybackTime" options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionInitial context:&musicPlayer]; [self.musicPlayer addObserver:self forKeyPath:@"currentPlaybackTime" options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionInitial context:&musicPlayer]; I do get the initial values for currentPlaybackTime in: -(void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context but I never get any calls when the player is playing the song (the whole point). If I set the currentPlaybackTime to a specific value (locating manually using a slider), I get calls with the values I set (useless since I know what I am setting them to). How are we supposed to track the playback time without just polling it constantly?

Hey, I've been trying to fetch my Apple Music recently played songs for an app I'm working on, and I want to access the lastPlayedDate field. If I'm not mistaken, this field should exist for a Song according to Apple's documentation: https://developer.apple.com/documentation/musickit/song/lastplayeddate However, whenever I try to fetch this data, the lastPlayedDate field is always nil. All the other data I'm looking for, however, seems to fetch without issue. Here's the code I'm using: //Request as described in Apple MusicKit //https://developer.apple.com/documentation/musickit/musicrecentlyplayedrequestable var request = MusicRecentlyPlayedRequest<Song>() request.limit=30 do { let response = try await request.response() let songs = response.items.compactMap { song -> RecentlyPlayedSong? in let songName = song.title let songArtist = song.artistName let songAlbum = song.albumTitle let artwork: MusicArtworkType let preview_url = song.previewAssets?.first?.url?.absoluteString if let appleMusicArtwork = song.artwork { print("Found a song, \(song) with lastPlayedDate \(song.lastPlayedDate)") artwork = .AppleMusic(appleMusicArtwork) return RecentlyPlayedSong(name: songName, artist: songArtist, album: songAlbum, artwork: artwork, preview_url: preview_url, lastPlayedDate: song.lastPlayedDate ?? Date()) } I'm trying to map the response into a custom struct I made, but here's a sample of what's getting printed to the logs: Found a song, Song(id: "1676362342", title: "pwdr Blu (feat. Brother.)", artistName: "Kx5, deadmau5 & Kaskade") with lastPlayedDate nil Found a song, Song(id: "881289980", title: "Worlds Apart (feat. Kerli)", artistName: "Seven Lions") with lastPlayedDate nil Found a song, Song(id: "1501540431", title: "What’s Done Is Done", artistName: "Seven Lions & HALIENE") with lastPlayedDate nil Even though I just listened to these songs a a few minutes ago. Anyone ever run into this issue before? Any settings I need to look at changing to get this to show?

I'm making a request to get 10 artists with their top songs at once, but for some artists it will always fail with a 504. The response is also in HTML which leads to a decoding error. This is my code var request = MusicCatalogResourceRequest<Artist>(matching: \.id, memberOf: ids) request.properties = properties let response = try await request.response() where ids is MusicItemId. Below I have an input which will always fail 100% of the time, even when retried. 10 elements  - 0 : "51639"  - 1 : "331584"  - 2 : "120199"  - 3 : "45058"  - 4 : "284786497"  - 5 : "44984"  - 6 : "37299"  - 7 : "518462"  - 8 : "39525"  - 9 : "73568" Example response: [DataRequesting] Failed to parse body of response with status code Unknown (504):  <!DOCTYPE html> <html lang="en"> <head>   <style>     body {       font-family: "Helvetica Neue", "HelveticaNeue", Helvetica, Arial, sans-serif;       font-size: 15px;       font-weight: 200;       line-height: 20px;       color: #4c4c4c;       text-align: center;     }     .section {       margin-top: 50px;     }   </style> </head> <body> <div class="section">   <h1>&#63743;</h1>   <h3>Gateway Timeout</h3>   <p>Correlation Key: WFRI6Q5HXAUJYXGNRKQ6YTBYIM</p> </div> </body> </html> I have also tried batching these into 2 requests of 5 artists instead of 1 request of 10 artists which still fails. However, I do have sets of 10 artists that work fine. Anyone know why?

I'm slowly learning the new MusicKit beta for swift. I've learned to successfully retrieve tracks of type Song using MusicDataRequest, using the following: ... let countryCode = try await MusicDataRequest.currentCountryCode if let url = URL(string: "https://api.music.apple.com/v1/catalog/\(countryCode)/songs?filter[isrc]=\(isrc)") {   let dataRequest = MusicDataRequest(urlRequest: URLRequest(url: url))   let dataResponse = try await dataRequest.response() ... However, when I decode the data, there does not seem to be any album information that I can see. I've tried adding includes=albums to the URL, but I don't think that's the right approach, because when I veiw the Song struct in MusicKit, I don't see a reference to an Album type anywhere. Any advice on how to retrieve the album information would be most appreciated. Thanks.

When accessing the REST API, If you apply "include=albums" to a 'catalog//songs' endpoint requests with a filter on ISRC, the API will, without fail, return a 504 error status. If you remove the 'include=albums' and/or replace it with something like 'include=artists' it works fine. This has been like this for months and we need to get album details back with these requests. Could the Apple team please respond and verify the issue as it's blocking production for us. Thanks.

Hello. I have the following question. I call the nextBatch() method on MusicItemCollection to get the next collection of artist albums. Here is my method: func allAlbums2(artist: Artist) async throws -> [Album] { var allAlbums: [Album] = [] artist.albums?.forEach { allAlbums.append($0) } guard let albums = artist.albums else { return [] } var albumsCollection = albums while albumsCollection.hasNextBatch { let response = try await albumsCollection.nextBatch() if let response { albumsCollection = response var albums = [Album]() albumsCollection.forEach({ albums.append($0)}) allAlbums.append(contentsOf: albums) } } return allAlbums } The problem is as follows. Sometimes it happens that some albums not in nextBatch are not returned (I noticed one, I didn't check the others). This happens once every 50-100 requests. The number of batches is returned the same when the album is skipped. The same albums are returned in the batch where the album was missed. I have a question, do I have a problem with multi-threading or something else or is it a problem in the API. The file contains prints of the returned batches. One with a missing album, the other without a missing one. There are about 3000 lines in the file. I will be grateful for a hint or an answer. Thank you!

Has anyone found a way to retrieve user token if I want to make an app on Flutter that uses that to make Apple Music API calls to just retrieve the user data and display it on the application? Something like when a user opens their app, there is a button that says connect with apple. It takes the user to give permissions for apple music and that retrieves their user token. I know there is Music Kit on Swift but i wonder if there is something like that on flutter

We are looking at potentially adding access to Apple Music Classical into a game we have with classical music. I cannot find any documentation that states if MusicKit can access the subscription content on Apple Music Classical. We would prefer to give our players the option to play with the higher quality subscription music if desired. Thank you in advance for your assistance.

I am trying to get the playbackStoreID via the MPMediaPickerController so I can play songs in my app. For many songs I can see and select I am getting a value of "0" for the playbackStoreID on the returned MPMediaItem. Now if I use the "Music" app I can play those songs, but since the playbackStoreID is "0" I cannot successful get them in the queue for a MPMusicPlayerController.applicationQueuePlayer What's the deal? How do I get a proper ID that I can use to get those songs played? If I cannot, how can I hide those songs from the MPMediaPickerController so a user does not think they can play those songs in my app?

Hi, Is there any reasonable way to use MusicKit on the Vision Pro simulator. I have been unable to get anything working and I was wondering if the situation is the same as iOS etc where you need a physical device to test the app.

I'm getting a variety of errors when I call prepareToPlay on the MPMusicPlayerController. Sometimes they happen, sometimes they don't. I'm trying to play songs from the Apple Music service. When I don't get the errors, it plays just fine. I have iOS v13.5.1 on my iPhone Xs and I'm using Xcode 11.5. This is my code: let applicationMusicPlayer = MPMusicPlayerController.applicationMusicPlayer applicationMusicPlayer.setQueue(with: [trackID]) applicationMusicPlayer.prepareToPlay(completionHandler:{ error in if let error = error { print(error.localizedDescription) return } DispatchQueue.main.async{ applicationMusicPlayer.play() } } These are the various errors I'm getting: [SDKPlayback] Failed to prepareToPlay error: Error Domain=MPMusicPlayerControllerErrorDomain Code=2 "Queue was interrupted by another queue" UserInfo={NSDebugDescription=Queue was interrupted by another queue} [SDKPlayback] Failed to prepareToPlay error: Error Domain=MPMusicPlayerControllerErrorDomain Code=9 "Preparing queue timed out" UserInfo={NSDebugDescription=Preparing queue timed out} [SDKPlayback] Failed to prepareToPlay error: Error Domain=MPMusicPlayerControllerErrorDomain Code=6 "Failed to prepare to play" UserInfo={NSDebugDescription=Failed to prepare to play} [SDKPlayback] applicationQueuePlayer _establishConnectionIfNeeded timeout [ping did not pong]

I need to duck the audio coming from ApplicationMusicPlayer while playing a local file using AVAudioPlayer. I've tried using the duckOthers option as follows, but it doesn't work: let appAudioSession = AVAudioSession.sharedInstance() do { try appAudioSession.setCategory(.playAndRecord, mode: .default, options: .duckOthers) Maybe this is because there's one session for the entire app, and ApplicationMusicPlayer is using it? This is a fairly critical problem for my application, since Music content is always much louder than locally recorded content. Any insight appreciated.
