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

I'm trying to set a specific start time for the song, using ApplicationMusicPlayer.shared.playbackTime but is not working musicPlayer.playbackTime = 10 try await musicPlayer.prepareToPlay() try await musicPlayer.play()

Since iOS 12 it has become difficult to detect the end of playback using the system music player. In earlier iOS versions, the now playing item would be set nil and you would receive a notification that the player stopped. In iOS 12 and later, nowPlayingItem still contains the current song and the only notification you get is MPMusicPlayerControllerPlaybackStateDidChangeNotification with the playbackState set to MPMusicPlaybackStatePaused. Pressing pause in my car (or any remote access) generates the same conditions making it difficult to correctly detect the difference. It would be nice if they added a notification that playback was done (similar to the other players). Any suggestions?

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?

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.

I am using MusicKit ApplicationMusicPlayer to play music in my app. Everything works fine as long as I'm not playing large playlists that contain hundreds of songs. When I to play collection of songs that is larger than around 300 I'm always getting the error message saying: "Prepare to play failed" UserInfo={NSDebugDescription=Prepare to play failed, NSUnderlyingError=0x121d42dc0 {Error Domain=MPMusicPlayerControllerErrorDomain Code=9 "Remote call timed out" UserInfo={NSDebugDescription=Remote call timed out}}})) It doesn't matter if songs are downloaded to the device or not. I am aware that there is another initializer for player's queue that accepts Playlist instances but in my app users can choose to sort playlist tracks in different order than the default and that makes using that initializer not feasible for me. I tried everything I could think of, I tried to fall back on MPMusicPlayerController and pass array of MPMusicPlayerPlayParameters to it but the result was the same. typealias QueueEntry = ApplicationMusicPlayer.Queue.Entry let player = ApplicationMusicPlayer.shared let entries: [QueueEntry] = tracks .compactMap { guard let song = $0 as? Song else { return nil } return QueueEntry(song) } Task(priority: .high) { [player] in do { player.queue = .init(entries, startingAt: nil) try await player.play() // prepareToPlay failed } catch { print(error) } }

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!

Hello, Problem I am having the exact same issue as described here : https://forums.developer.apple.com/forums/thread/693310 From my understanding of the answers on this topic, it appears to be a problem on the Server Side.

Hi, Is it possible to get the various audio variants for a given song ID, I am unable to find any documentation for this online. In particular, could I see if Dolby Atmos is available for the track? Here is an example of a request I am sending: https://api.music.apple.com/v1/catalog/us/songs/1168770969

In SwiftUI there is a built-in component for displaying album artworks called Artwork but there is no equivalent for UIKit. My current approach is to use the .url() method to read image's URL and download the image or read it from the disk but the performance is much worse than it was previously with MPMediaItem's artworkImage method. let artworkQueue = DispatchQueue( label: "MusicKit-ArtworkQueue", qos: .default, attributes: .concurrent ) let artworkSemaphore = DispatchSemaphore(value: 5) extension Song { func artworkImage(for size: CGSize, completion: @escaping (UIImage?) -> Void) { artworkQueue.async { artworkSemaphore.wait() defer { artworkSemaphore.signal() } let imageURL = artwork?.url( width: Int(size.width), height: Int(size.height) ) // I hate doing this as it might very well break in the future guard let imageURL, imageURL.scheme == "musicKit" else { return completion(nil) } guard let imageData = try? Data(contentsOf: imageURL), let image = UIImage(data: imageData) else { return completion(nil) } completion(image) } } } I really dislike this approach because it feels hacky but somewhat works. You might ask what's the semaphore for? Well, without it I could notice that MusicKit was choking and after reading too many artworks at once. Can someone from Apple please provide us with an example on how to use MusicKit with UIKit properly? Ideally (IMO) we would have a method defined on Song and other MusicKit structures that returns the image for us, just like MPMediaItem had the .artwork() method. It would make our lives so much easier.

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 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 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.

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...
