import UIKit
import AVFoundation

class PlaySoundViewController: UIViewController {
    var audioplayer: AVAudioPlayer!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        if var filePath = NSBundle.mainBundle().pathForResource("movie_quote", ofType: "mp3") {
            var fileUrl = NSURL.fileURLWithPath(filePath)
            audioplayer = AVAudioPlayer(contentsOfURL: fileUrl, error: nil)


        }else{
        println("path file is empty")
        }
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()

    @IBAction func PlaySoundSlow(sender: UIButton) {
        audioplayer.play()
    }

Answer 1

I generally make a sound class, then use a function to call the sound into play, like this:

Sound Class:

class Sound {
    //properties
    var fileName = ""
    var fileExtension = ""

    //custom init
    init(fileName: String, fileExtension: String) {
        self.fileName = fileName
        self.fileExtension = fileExtension
    }
}

playSound Function:

// requires AVAudioPlayer? instance

// requires AVFoundation import

// requires AVAudioPlayerDelegate

var audioPlayer: AVAudioPlayer()

func playSound (sound: Sound) {

let dispatchQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)

 dispatch_async(dispatchQueue, {[weak self] in let mainBundle = NSBundle.mainBundle() /* Find the location of our file to feed to the audio player */ let filePath = mainBundle.pathForResource(sound.fileName, ofType:sound.fileExtension) if let path = filePath{ let fileData = NSData(contentsOfFile: path) var error:NSError? /* Start the audio player */ self!.audioPlayer = AVAudioPlayer(data: fileData, error: &error) /* Did we get an instance of AVAudioPlayer? */ if let player = self!.audioPlayer{ /* Set the delegate and start playing */ player.delegate = self if player.prepareToPlay() && player.play(){ /* Successfully started playing */ } else { /* Failed to play */ } } else { /* Failed to instantiate AVAudioPlayer */ } } }) 

Hopefully this helps you.
