Creating and playing a sound in swift

Question

So what I want to do is create and play a sound in swift that will play when I press a button, I know how to do it in Objective-C, but does anyone know how to in Swift?

It would be like this for Objective-C:

NSURL *soundURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"mysoundname" ofType:@"wav"]];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)soundURL, &mySound);

And then to play it I would do:

AudioServicesPlaySystemSound(Explosion);

Does anyone know how I could do this?

The root of this question is how to call C functions from swift. I am curious about this also. — 67cherries, Jun 04 '14 at 17:39
this line can create the sound url: `var url :NSURL = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("mysoundname", ofType: "wav"))` — Connor Pearson, Jun 04 '14 at 17:39
@connor Thanks that works but what about for AudioServicesCreateSystemSoundID — Jacob Banks, Jun 04 '14 at 17:46
I'm not sure about that. I've only been able to call the objective-c api from swift. — Connor Pearson, Jun 04 '14 at 17:47

This is similar to some other answers, but perhaps a little more "Swifty":

// Load "mysoundname.wav"
if let soundURL = Bundle.main.url(forResource: "mysoundname", withExtension: "wav") {
    var mySound: SystemSoundID = 0
    AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
    // Play
    AudioServicesPlaySystemSound(mySound);
}

Note that this is a trivial example reproducing the effect of the code in the question. You'll need to make sure to import AudioToolbox, plus the general pattern for this kind of code would be to load your sounds when your app starts up, saving them in SystemSoundID instance variables somewhere, use them throughout your app, then call AudioServicesDisposeSystemSoundID when you're finished with them.

You also need to import AudioToolbox – Brody Robertson Sep 20 '15 at 05:25

Do you need to call `AudioServicesDisposeSystemSoundID(mySound)` to free up the memory later on? if you do it right away the sound basically doesn't play (gets cleaned up instantly) so I did `dispatch_after` and cleaned it up 10 seconds later. – owenfi Sep 21 '15 at 07:08
@owenfi The fragment of code in my answer is just the Swift equivalent of the fragment of code in the question. The general pattern for AudioServices is to load up your sounds when your app fires up, use them throughout the app, and dispose of them when the app closes, but each app will be different. – Matt Gibson Sep 21 '15 at 07:26
@ozgur Why are you using an out-of-date version of Xcode? We'll need to know what "not working" means, and you'll probably be better off asking a new question if you have specific issues. – Matt Gibson Feb 17 '16 at 12:02
actually this is the only way to play wav file. AVPlayer doesn't seem to work. – Haitao Aug 23 '17 at 22:57

Here's a bit of code I've got added to FlappySwift that works:

import SpriteKit
import AVFoundation

class GameScene: SKScene {

    // Grab the path, make sure to add it to your project!
    var coinSound = NSURL(fileURLWithPath: Bundle.main.path(forResource: "coin", ofType: "wav")!)
    var audioPlayer = AVAudioPlayer()

    // Initial setup
    override func didMoveToView(view: SKView) {
        audioPlayer = AVAudioPlayer(contentsOfURL: coinSound, error: nil)
        audioPlayer.prepareToPlay()
    }

    // Trigger the sound effect when the player grabs the coin
    func didBeginContact(contact: SKPhysicsContact!) {
        audioPlayer.play()
    }

}

It would seem you could just declare audioPlayer right before using it, but that didn't work for me in the simulator. I had to declare it at the top just like you did. – Adam Loving Oct 30 '14 at 19:02
@Adam Loving you can declare audioPlayer right before using it, but make sure you invoke play() in the same function you declared it (as opposed to the good answer) Further, I would declare `coinSound` and `audioPlayer` with `let` instead of `var` since you do not want to change these objects at a later point in time. – fat32 Jan 28 '15 at 18:46

In Swift 2 remember to run it this way `do { (player object) } catch _ { }` or your will get a bug! :) – ParisNakitaKejser Jun 26 '15 at 20:02

Handy Swift extension:

import AudioToolbox

extension SystemSoundID {
    static func playFileNamed(fileName: String, withExtenstion fileExtension: String) {
        var sound: SystemSoundID = 0
        if let soundURL = NSBundle.mainBundle().URLForResource(fileName, withExtension: fileExtension) {
            AudioServicesCreateSystemSoundID(soundURL, &sound)
            AudioServicesPlaySystemSound(sound)
        }
    }
}

Then, from anywhere in your app (remember to import AudioToolbox), you can call

SystemSoundID.playFileNamed("sound", withExtenstion: "mp3")

to play "sound.mp3"

This creates a SystemSoundID from a file called Cha-Ching.aiff.

    let soundURL = CFBundleCopyResourceURL(CFBundleGetMainBundle(), "Cha-Ching", "aiff", nil)
    AudioServicesCreateSystemSoundID(soundURL, &soundID)

var mySound = NSSound(named:"Morse.aiff")
mySound.play()

"Morse.aiff" is a system sound of OSX, but if you just click on "named" within XCode, you'll be able to view (in the QuickHelp pane) where this function is searching the sounds. It can be in your "Supporting files" folder

According to new Swift 2.0 we should use do try catch. The code would look like this:

var badumSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("BadumTss", ofType: "mp3"))
var audioPlayer = AVAudioPlayer()
 do {
     player = try AVAudioPlayer(contentsOfURL: badumSound)
 } catch {
     print("No sound found by URL:\(badumSound)")
 }
 player.prepareToPlay()

First Add SpriteKit and AVFoundation Framework.

 func playEffectSound(filename: String){
