Why not create a music helper class that you can access from anywhere. Either the singleton way or a class with static methods. This should also make your code cleaner and easier to manage.

I would also split the setup method and the play method so that you do not set up the player each time you play the file.

e.g Singleton

class MusicManager {

    static let shared = MusicManager()

    var audioPlayer = AVAudioPlayer()


    private init() { } // private singleton init


    func setup() {
         do {
            audioPlayer =  try AVAudioPlayer(contentsOf: URL.init(fileURLWithPath: Bundle.main.path(forResource: "music", ofType: "mp3")!))
             audioPlayer.prepareToPlay()

        } catch {
           print (error)
        }
    }


    func play() {
        audioPlayer.play()
    }

    func stop() {
        audioPlayer.stop()
        audioPlayer.currentTime = 0 // I usually reset the song when I stop it. To pause it create another method and call the pause() method on the audioPlayer.
        audioPlayer.prepareToPlay()
    }
}

When your project launches just call the setup method

MusicManager.shared.setup()

Than from any where in your project you can say

MusicManager.shared.play()

to play the music.

To than stop it just call the stop method

MusicManager.shared.stop()
