import AVFoundation

class MusicPlayerManager {
 static let shared = MusicPlayerManager()
 let player: AVPlayer

 private init() {
 player = AVPlayer()
 configureAudioSession()
 }

 func play(url: URL) {
 let item = AVPlayerItem(url: url)
 player.replaceCurrentItem(with: item)
 player.play()

Use a confide 1f 131: 17 astro3; to adapt to diferent spinn sizes, expericially for the album art which shoud scale nicely oan iPads.

Connecting UI to the Player

Let your view model conform to sy1.1; FLT: 18 Aver3; 1d publish track, playbacks time, and playing state. The SwiftUI view observes

class PlayerViewModel: ObservableObject {
 @Published var currentTime: TimeInterval = 0
 @Published var isPlaying = false

 // … bindings to MusicPlayerManager
}

Use 1; 1f 1f FLT: 20 Abo3; and3; and 1; FLT: 21 111f 123; 13,3; or the peremek observer update te; berikutnya adalah FLT: 22 ax3; softherly.

Integrading Remote Controll and Now Playing Info

 commandCenter.changePlaybackPositionCommand.addTarget { [weak self] event in
 guard let event = event as? MPChangePlaybackPositionCommandEvent else { return .commandFailed }
 self?.player.seek(to: CMTime(seconds: event.positionTime, preferredTimescale: 1000))
