AVAudioPlayer not playing audio in Swift

Question

I have this code in a very simple, single view Swift application in my ViewController:

var audioPlayer = AVAudioPlayer()

@IBAction func playMyF         


        

Answer 1

var audioPlayer = AVAudioPlayer()
var alertSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("KiepRongBuon", ofType: "mp3")!)
        AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)
        AVAudioSession.sharedInstance().setActive(true, error: nil)
        var error:NSError?
        audioPlayer = AVAudioPlayer(contentsOfURL: alertSound, error: &error)
        audioPlayer.prepareToPlay()
        audioPlayer.play()
