Answer 1

You should make audioPlayer an instance variable global. This code will have it deallocated immediately after calling .play()

class ViewController: UIViewController {

    var audioPlayer = AVAudioPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()

        if NSFileManager.defaultManager().fileExistsAtPath(pathString){
        let url = NSURL(fileURLWithPath:pathString, isDirectory: false)
        AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)
        AVAudioSession.sharedInstance().setActive(true, error: nil)

        var error:NSError?
        audioPlayer = AVAudioPlayer(contentsOfURL: url, error: &error)
        audioPlayer.prepareToPlay()
        audioPlayer.play()
    }
}
}
