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)") } }
