Hi, I'm developing a musicKit integration in my iOS App, and I want to select songs from recently played (done it), the problem is that the queue is not auto-generated and the user have to select other song if they want to go forward. There is any method to ask for similar songs, or recommended songs, from a song that the user has already selected? It will be really great :) Also if you know it... There is any publisher for the music duration or I need to do a timer?? Thanks. David.

After an Album, Playlist, or collection of songs have been added to the ApplicationMusicPlayer queue, clearing the queue can be easily accomplished with: ApplicationMusicPlayer.shared.queue.entries = [] This transitions the player to a paused state with an empty queue. After queueing a Station, the same code cannot be used to clear the queue. Instead, it causes the queue to be refilled with a current and next MusicItem from the Station. What's the correct way to detect that the ApplicationMusicPlayer is in the state where it's being refilled by a Station and clear it? I've tried the following approaches with no luck: # Reinitialize queue ApplicationMusicPlayer.shared.queue = ApplicationMusicPlayer.Queue() # Create empty Queue let songs: [Song] = [] let emptyQueue = ApplicationMusicPlayer.Queue(for: songs) ApplicationMusicPlayer.shared.queue = emptyQueue

I am building an app for MacOS and I am trying to implement the code to add songs to a library playlist (which is added below). The issue I am having is that if I use Music Kit to load a users library playlists, the ID for the playlist (which is just a string of numbers) does not work with the Add tracks to a Library Playlist endpoint of Apple Music API. If I retrieve the playlists from the Apple Music API and use that playlist ID (which is different than the id I get from MusicKit) my code works fine and adds the song to the playlist. The problem is that when getting a users library playlists from Apple Music API is that it does not give me all of the library playlists that I get when using Music Kit and it also does not give me Artwork for playlists that have the collage of album covers, so I would prefer to use Music Kit to get the playlists. I have also tested trying to retrieve a single playlist using the Apple Music API with the playlist Id from Music Kit and it does not work. I get the error that the resource cannot be found. Since this is a macOs app I cannot use MusicKit to add songs to library playlists. Does anyone know a way to resolve this? Or a possible workaround? Ideally I want to use MusicKit to get the library playlists and have some way to use the playlist Id and add songs to that playlist. Below is my code for adding a song to a playlist using the Apple Music API, which works correctly only if I originally get the library playlist's id value from a playlist retrieved from the Apple Music API. Also, does anyone know why the playlist Id's are not universal and are different when using Music Kit and Apple Music API? For songs and tracks it does not seem to matter if I use music kit or Apple Music API, the Id's are in the correct format for Apple Music API to use and work with my code. Thanks everyone for any and all help! func addToPlaylist(songs: [Track], playlist: Playlist, alert: Binding<AlertItem?>) async { let tracks = AppleMusicPlaylistPostRequestBody(data: songs.compactMap { AppleMusicPlaylistPostRequestItem(id: $0.id.rawValue, type: "songs") // or "library-songs" }) let playlistID = playlist.id // Build the request URL for adding a song to a playlist guard let url = URL(string: "https://api.music.apple.com/v1/me/library/playlists/\(playlistID)/tracks") else { alert.wrappedValue = AlertItem(title: "Error", message: "Invalid URL for the playlist.") return } // Authorization Header guard let musicUserToken = try? await MusicUserTokenProvider().getUserMusicToken() else { alert.wrappedValue = AlertItem(title: "Error", message: "Unable to retrieve Music User Token.") return } do { var request = URLRequest(url: url) request.httpMethod = "POST" request.setValue("Bearer \(musicUserToken)", forHTTPHeaderField: "Authorization") request.setValue("application/json", forHTTPHeaderField: "Content-Type") let encoder = JSONEncoder() let data = try encoder.encode(tracks) request.httpBody = data let musicRequest = MusicDataRequest(urlRequest: request) let musicRequestResponse = try await musicRequest.response() // Check if the request was successful (status 201) if musicRequestResponse.urlResponse.statusCode == 201 { alert.wrappedValue = AlertItem(title: "Success", message: "Song successfully added to the playlist.") } else { print("Status Code: \(musicRequestResponse.urlResponse.statusCode)") print("Response Data: \(String(data: musicRequestResponse.data, encoding: .utf8) ?? "No Data")") // Attempt to decode the error response into the AppleMusicErrorResponse model if let appleMusicError = try? JSONDecoder().decode(AppleMusicErrorResponse.self, from: musicRequestResponse.data) { let errorMessage = appleMusicError.errors.first?.detail ?? "Unknown error occurred." alert.wrappedValue = AlertItem(title: "Error", message: errorMessage) } else { alert.wrappedValue = AlertItem(title: "Error", message: "Failed to add song to the playlist.") } } } catch { alert.wrappedValue = AlertItem(title: "Error", message: "Network error: \(error.localizedDescription)") } }

Having an issue playing songs fetched with MusicKit but only on release builds, ApplicationMusicPlayer.shared.prepareToPlay() throws "The operation couldn’t be completed. (MPMusicPlayerControllerErrorDomain error 6.)" The authorization status is .authorized The debug version of the app works perfectly. Here is my project for the reference. Thank you. macOS 15.0.1, Xcode 16.0

Hello, I have a command line application that uses iTunesLibrary to "save" the state of what I have listened to. I have it run every night via a LaunchAgent. You can see the source here: https://github.com/bolsinga/itunes_json Prior to Sequoia it would run nightly. I'd just have to grant it access to the Music library once, and it would be fine thereafter. However with Sequoia it requires UI interaction to grant it access every time. This makes it no longer run unattended overnight, defeating its purpose. I have the console logs of when this happens. You can see it in my issue tracking it here: https://github.com/bolsinga/itunes_json/issues/410 One thing that makes me wonder is that it is a command line application, not a bundle. How do I make a command line application get access to MusicKit / iTunesLibrary, and keep it thereafter? I'd like to get my pre-Sequoia behavior back. I've filed FB15592660 too. I've granted it access to run in the background, as well as access to my Music library (please see attached screenshots).

I'm trying to get the item that's assigned to the currentEntry when playing any song which is currently coming up nil when the song is playing. Note currentEntry returns: MusicPlayer.Queue.Entry(id: "evn7UntpH::ncK1NN3HS", title: "SONG TITLE") I'm a bit stumped on the API usage. if the song is playing, how could the queue item be nil? if queueObserver == nil { queueObserver = ApplicationMusicPlayer.shared.queue.objectWillChange .sink { [weak self] in self?.handleNowPlayingChange() } } } private func handleNowPlayingChange() { if let currentItem = ApplicationMusicPlayer.shared.queue.currentEntry { if let song = currentItem.item { self.currentlyPlayingID = song.id self.objectWillChange.send() print("Song ID: \(song.id)") } else { print("NO ITEM: \(currentItem)") } } else { print("No Entries: \(ApplicationMusicPlayer.shared.queue.currentEntry)") } }

I have an app that gets data from Music.app with both the iTunesLibrary and MusicKit. iTunesLibrary has ITLibArtist.sortName and ITLibAlbum.sortTitle and ITLibAlbum.sortAlbumArtist. I can’t seem to find an equivalent in MusicKit. How are those properties obtained using MusicKit? Thanks. FYI I have filed FB15554956 on this. You also may see my code at https://github.com/bolsinga/itunes_json

Is anyone developing a way for users to control an iOS or PadOS device playing Apple Music to a DAC via USB to amp from another iOS or PadOS device wirelessly? Specifically, full control. Not Accessibility, not to Apple TV, not HomePods, not firmware downgraded Airport Expresses to a DAC or other hacks mentioned for the past decade this “connect” like feature has been desired by audiophiles seeking exclusive mode on a device with that (iOS/PadOS) but — control it while sitting on a couch or in a wheel chair across the room. Exclusive mode being the key feature iOS and PadOS offer that is desired with full or nearly full Apple Music control.

Hi all, I am working with MusicKit and have managed to get a user's recommendation playlists (favorites, get up, etc). Isolating just one, I am trying to access the tracks in there using .tracks but it returns nothing. Wondering if I am doing something wrong or if these don't have tracks necessarily associated with them. Code is below (not everything just kinda where I am accessing the playlist) try await requestMusicAuthorization() let request = MusicPersonalRecommendationsRequest() let response = try await request.response() guard let madeForYou = response.recommendations.first(where: { $0.title == "Made for You" }) else { throw NSError(domain: "RecommendationError", code: 0, userInfo: [NSLocalizedDescriptionKey: "No 'Made for You' recommendation found."]) } guard let firstPlaylist = madeForYou.playlists.first else { throw NSError(domain: "PlaylistError", code: 1, userInfo: [NSLocalizedDescriptionKey: "No playlists found in 'Made for You' recommendation."]) } print("Fetching tracks for playlist: \(firstPlaylist.name ?? "Unknown")") let playlistRequest = MusicCatalogResourceRequest<Playlist>(matching: \.id, equalTo: firstPlaylist.id) let playlistResponse = try await playlistRequest.response() guard let playlist = playlistResponse.items.first else { throw NSError(domain: "PlaylistError", code: 2, userInfo: [NSLocalizedDescriptionKey: "Couldn't fetch the playlist details."]) } guard let tracks = playlist.tracks else { throw NSError(domain: "PlaylistError", code: 3, userInfo: [NSLocalizedDescriptionKey: "No tracks found in the playlist."]) }

Hi, I've recently been working with the Apple Music API and have had success in loading all the playlists on my account, loading songs from each playlist, and adding songs to the ApplicationMusicPlayer.share.queue. The problem I'm running into is that not all songs from the playlist are being added to the queue, despite confirming all the songs are being based on the PlaybackView.swift I'm about to share with you. I would also like to answer other underlying questions if possible. I am also open to any other suggestions. In this scenario were also assuming isShuffled is true every time. How can I determine when a song has ended? How can I get the album title information? How can I get the current song title, album information, and artist information without pressing play? I can only seem to update the screen when I select my play meaning ApplicationMusicPlayer.shared.play() is being called. How do I get the endTime of the song? I believe it should be ApplicationMusicPlayer.shared.queue.currentEntry.endTime but this doesn't seem to work. // // PlayBackView.swift // // Created by Justin on 8/16/24. // import SwiftUI import MusicKit import Foundation enum PlayState { case play case pause } struct PlayBackView: View { @State var song: Track @Binding var songs: [Track]? @State var isShuffled = false @State private var playState: PlayState = .pause @State private var isFirstPlay = true private let player = ApplicationMusicPlayer.shared private var isPlaying: Bool { return (player.state.playbackStatus == .playing) } var body: some View { VStack { // Album Cover HStack(spacing: 20) { if let artwork = player.queue.currentEntry?.artwork { ArtworkImage(artwork, height: 100) } else { Image(systemName: "music.note") .resizable() .frame(width: 100, height: 100) } VStack(alignment: .leading) { // Song Title Text(player.queue.currentEntry?.title ?? "Song Title Not Found") .font(.title) .fixedSize(horizontal: false, vertical: true) // How do I get AlbumTitle from here?? // Artist Name Text(player.queue.currentEntry?.subtitle ??

I have a recent post kind of outlining a similar question here. This time though I'm confident that inserting an array of Track works when inserting into the ApplicationMusicPlayer.shared.queue but now I'm not sure how I can initialize the queue to display song title and artwork for example. I'm also not sure how to get the current item in the queue's artist information and album information which I feel should be easy to do so maybe I'm missing something obvious. Hope this paints of what I'm trying to do and I'm going to post the neccessary code here to help me debug/figure out this problem. import SwiftUI import MusicKit struct PlayBackView: View { @Environment(\.scenePhase) var scenePhase @Environment(\.openURL) private var openURL // Adding Enum Here for Question Sake enum PlayState { case play case pause } @State var song: Track @Binding var songs: [Track]? @State var isShuffled = false @State private var playState: PlayState = .pause @State private var songTimer: Int = Int.random(in: 5...30) @State private var roundTimer: Int = 5 @State private var isTimerActive = false // @State private var volumeValue = VolumeObserver() @State private var isFirstPlay = true @State private var isDancing = false @State private var player = ApplicationMusicPlayer.shared private var isPlaying: Bool { return (player.state.playbackStatus == .playing) } let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect() var playPauseImage: String { switch playState { case .play: "pause.fill" case .pause: "play.fill" } } var body: some View { VStack { // Album Cover HStack(spacing: 20) { if let artwork = player.queue.currentEntry?.artwork { ArtworkImage(artwork, height: 100) } else { Image(systemName: "music.note") .resizable() .frame(width: 100, height: 100) } VStack(alignment: .leading) { /* This is where I want to display song title, album title, and artist name for example */ // Song Title Text(player.queue.currentEntry?.title ??

Hi there, After upgrading to iOS 18, I noticed that ApplicationMusicPlayer.Queue behavior has broken if at least one song that is added to the queue is also in to the Apple Music Library on the device. The resulting behavior is that the queue does not accept all the items, and only items that are in the Library are playable in the queue. The expected behavior and the previous behavior on iOS 17 was that all the items would be added to the queue successfully. I confirmed this behavior on a separate test device running iOS 17.7. The items added are all being fetched via MusicCatalogResourceRequest<Song> so I would expect that a requested song being present in the library would have no effect.

I have an app on which users learn choreography. To avoid copyright infringements we currently only have audio instructions and no music on the app. Could we enable those that are subscribed to Apple Music to listen to the part of a song the corresponds to the choreography? Usually they are 60 seconds long. The app is in React Native. Would it be possible to implement it so that opening a dance video automatically triggers the playback of that song from e.g. second 32 - 95? Since the video is looping, could it then start playing from second 32 again? Also looking for devs with experience in integrating the MusicKit for this usecase if it turns out to be possible.

Hi, In my app I am using MusicLibraryRequest<Artist> to fetch all of the artists in someone's Library collection. With this response I then fetch each artists albums: artist.with([.album]). The response from this only gives albums in the users Library collection. I would like to augment it with all of the albums for an artist from the full catalogue. I'm using MusicKit and targeting iOS18 and visionOS 2. Could someone please point me towards the best way to approach this?

It's simple to reproduce. The bug is simply when you queue a bunch of songs to play, it will always queue less than what you gave it. Here, I'm attempting to play an apple curated playlist, it will only queue a subset, usually less than 15, but as low as 1 out of 100. Use the system's forward and backwards to test it out. Here is the code, just paste it in to the ContentView file and make sure you have the capibility to run it. import SwiftUI import MusicKit struct ContentView: View { var body: some View { VStack{ Button("Play Music") { Task{ await playMusic() } } } } } func getOnlySongsFromTracks(tracks:MusicItemCollection<Track>?) async throws ->MusicItemCollection<Song>?{ var songs:[Song]? if let t = tracks{ songs = [Song]() for track in t { if case let .song(song) = track { songs?.append(song) print("track is song \(track.debugDescription)") }else{ print("track not song \(track.debugDescription)") } } } if let songs = songs { let topSongs = MusicItemCollection(songs) return topSongs } return nil } func playMusic() async { // Request authorization let status = await MusicAuthorization.request() guard status == .authorized else { print("Music authorization denied.") return } do { // Perform a hardcoded search for a playlist let searchTerm = "2000" let request = MusicCatalogSearchRequest(term: searchTerm, types: [Playlist.self]) let response = try await request.response() guard let playlist = response.playlists.first else { print("No playlists found for the search term '\(searchTerm)'.") return } // Fetch the songs in the playlist let detailedPlaylist = try await playlist.with([.tracks]) guard let songCollection = try await getOnlySongsFromTracks(tracks: detailedPlaylist.tracks) else { print("no songs found") return } guard let t = detailedPlaylist.tracks else { print("no tracks") return } // Create a queue and play let musicPlayer = ApplicationMusicPlayer.shared let q = ApplicationMusicPlayer.Queue(for: t) musicPlayer.queue = q try await musicPlayer.play() print("Now playing playlist: \(playlist.name)") } catch { print("An error occurred: \(error.localizedDescription)") } }

I am fetching playlist songs from the users library and also need the releaseDate (or year) for the song for my use case. However, the releaseDate is always nil since I have upgraded to sequoia. I am pretty sure, this was working before the upgrade, but I couldn't find any documentation on changes related to this. Furthermore I noticed, the IDs also now seem to be the catalog IDs instead of the global ones like i.PkdZbQXsPJ4DX04 Here's in a nutshell what I am doing func fetchSongs(playlist: Playlist) async throws { let detailedPlaylist = try await playlist.with([.tracks]) var currentTracks: MusicItemCollection<Track>? = detailedPlaylist.tracks repeat { for track in currentTracks! { guard case .song(let song) = track else { print("This is not a song") continue } print(song.releaseDate) } currentTracks = try await currentTracks?.nextBatch() } while currentTracks != nil }

A couple of weeks ago I got help here to play one song and the solution to my problem was that I wasn't adding the song (Track Type) to the queue correctly, so now I want to be able to add a playlist worth of songs to the queue. The problem is when I try to add an array of the Track type I get an error. The other part of this issue for me is how do I access an individual song off of the queue after I add it? I see I can do ApplicationMusicPlayer.shared.queue.currentItem but I think I'm missing/misunderstanding something here. Anyway's I'll post the code I have to show how I'm attempting to do this at this moment. In this scenario we're getting passed in a playlist from another view. import SwiftUI import MusicKit struct PlayBackView: View { @State var song: Track? @State private var songs: [Track] = [] @State var playlist: Playlist private let player = ApplicationMusicPlayer.shared VStack { // Album Cover HStack(spacing: 20) { if let artwork = player.queue.currentEntry?.artwork { ArtworkImage(artwork, height: 100) } else { Image(systemName: "music.note") .resizable() .frame(width: 100, height: 100) } VStack(alignment: .leading) { // Song Title Text(player.queue.currentEntry?.title ?? "Song Title Not Found") .font(.title) .fixedSize(horizontal: false, vertical: true) } } } .padding() .task { await loadTracks() // It's Here I thought I could do something like this player.queue = tracks // Since I can do this with one singular track player.queue = [song] do { try await player.queue.insert(songs, position: .afterCurrentEntry) } catch { print(error.localizedDescription) } } } @MainActor private func loadTracks() async { do { let detailedPlaylist = try await playlist.with([.tracks]) let tracks = detailedPlaylist.tracks ?? [] setTracks(tracks) } catch { print(error.localizedDescription) } } @MainActor private func setTracks(_ tracks: MusicItemCollection<Track>) { songs = Array(tracks) } }

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

How can I search for a single song by using its song ID? I tried the following code but it's not working: MusicCatalogResourceRequest(matching: Song.self, equalTo: song.id.rawValue) I get the following errors in Xcode: Cannot convert value of type 'Song.Type' to expected argument type 'KeyPath<MusicItemType.FilterType, String>' Generic parameter 'MusicItemType' could not be inferred I have the song ID saved as a string inside song so I just want to grab the full MusicKit MusicItemType from the API. I looked at the documentation but it doesn't make any sense to me. Please help!

I'm trying to create an app that uses the Apple Music API and while I can fetch playlists as I desire when selecting a song from a playlist the music does not play. First I'm getting the playlists, then showing those playlists on a list in a view. Then pass that "song" which is a Track type into a PlayBackView. There are several UI components in that view but I want to boil it down here for simplicity's sake to better understand my problem. struct PlayBackView: View { @State private var playState: PlayState = .pause private let player = ApplicationMusicPlayer.shared @State var song: Track private var isPlaying: Bool { return (player.state.playbackStatus == .playing) } var body: some View { VStack { AsyncImage(url: song.artwork?.url(width: 100, height: 100)) { image in image .resizable() .frame(maxWidth: .infinity) .aspectRatio(1.0, contentMode: .fit) } placeholder: { Image(systemName: "music.note") .resizable() .frame(width: 100, height: 100) } // Song Title Text(song.title) .font(.title) // Album Title Text(song.albumTitle ?? "Album Title Not Found") .font(.caption) // Play/Pause Button Button(action: { handlePlayButton() }, label: { Image(systemName: playPauseImage) }) .padding() .foregroundStyle(.white) .font(.largeTitle) Image(systemName: airplayImage) .font(ifDeviceIsConnected ? .largeTitle : .title3) } .padding() } private func handlePlayButton() { Task { if isPlaying { player.pause() playState = .play } else { playState = .pause await playTrack(song: song) } } } @MainActor public func playTrack(song: Track) async { do { try await player.play() playState = .play } catch { print(error.localizedDescription) } } } These are the errors I'm seeing printing in the console in Xcode prepareToPlay failed [no target descriptor] The operation couldn’t be completed.
