Hi there, I am seeing an error when attempting to prepareToPlay on iOS 15 Beta 5. I'm using SystemMusicPlayer's new .queue property directly as setQueue was deprecated. Are there other steps I should be doing to ensure that this method succeeds? Code: private func playAppleMusic(songs : [Song]) {     Task.init {         do {             print("0")             try await SystemMusicPlayer.shared.queue.insert(songs, position: .tail)             if (!SystemMusicPlayer.shared.isPreparedToPlay) {                 print("1")                 try await SystemMusicPlayer.shared.prepareToPlay()             }             print("2")             try await SystemMusicPlayer.shared.play()         } catch let error {             print("playAppleMusic error: \(error.localizedDescription)")         }     } } Result: 0 1 playAppleMusic error: The operation couldn’t be completed. (MPMusicPlayerControllerErrorDomain error 1.)

Code I'm using (paraphrased) private let player = ApplicationMusicPlayer.shared private func play(songs : [Song]) {     Task.init {         player.setQueue(with: songs)         try await player.prepareToPlay()         player.play()     } } When I compile and run on my device (iOS 15 Beta 4), the app SIGABRT crashes on launch (does not hit breakpoints) with: dyld[9429]: Symbol not found: _$s8MusicKit0A6PlayerC4playyyFTj   Referenced from: /private/var/containers/Bundle/Application/21A3E366-FDC0-481C-B857-99353C8BED87/Soundbooth.app/Soundbooth   Expected in: /System/Library/Frameworks/MusicKit.framework/MusicKit Symbol not found: _$s8MusicKit0A6PlayerC4playyyFTj   Referenced from: /private/var/containers/Bundle/Application/21A3E366-FDC0-481C-B857-99353C8BED87/Soundbooth.app/Soundbooth   Expected in: /System/Library/Frameworks/MusicKit.framework/MusicKit Has anyone else seen this behavior?
