Using Existing System Sounds in iOS App [Swift|

Play system sound in iOS 13

This worked:

AudioServicesPlaySystemSound(SystemSoundID(1104))

The list of all system sounds is available here: https://github.com/TUNER88/iOSSystemSoundsLibrary

How Can I Get A List of Available System Sounds in iOS?

Reading up on this, you can find code to get a list of system sound files - but only on a "jail break" device.

Based on this note on Apple's docs (link), it sounds like (sorry for the pun) we won't have much luck in trying to access the "internal" sound clips:

Note System-supplied alert sounds and system-supplied user-interface sound effects are not available to your iOS application. For example, using the kSystemSoundID_UserPreferredAlert constant as a parameter to the AudioServicesPlayAlertSound function will not play anything.

Playing system sound without importing your own

This code plays apple system sound "Tock.aiff"..I believe you can play different system sounds using this

NSString *path = [[NSBundle bundleWithIdentifier:@"com.apple.UIKit"] pathForResource:@"Tock" ofType:@"aiff"];
SystemSoundID soundID;
AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:path], &soundID);
AudioServicesPlaySystemSound(soundID);
AudioServicesDisposeSystemSoundID(soundID);

How to play a sound using Swift?

Most preferably you might want to use AVFoundation.
It provides all the essentials for working with audiovisual media.

Update: Compatible with Swift 2, Swift 3 and Swift 4 as suggested by some of you in the comments.

Swift 2.3

import AVFoundation

var player: AVAudioPlayer?

func playSound() {
    let url = NSBundle.mainBundle().URLForResource("soundName", withExtension: "mp3")!

    do {
        player = try AVAudioPlayer(contentsOfURL: url)
        guard let player = player else { return }

        player.prepareToPlay()
        player.play()

    } catch let error as NSError {
        print(error.description)
    }
}

---

Swift 3

import AVFoundation

var player: AVAudioPlayer?

func playSound() {
    guard let url = Bundle.main.url(forResource: "soundName", withExtension: "mp3") else { return }

    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        try AVAudioSession.sharedInstance().setActive(true)

        let player = try AVAudioPlayer(contentsOf: url)

        player.play()

    } catch let error {
        print(error.localizedDescription)
    }
}

Swift 4 (iOS 13 compatible)

import AVFoundation

var player: AVAudioPlayer?

func playSound() {
    guard let url = Bundle.main.url(forResource: "soundName", withExtension: "mp3") else { return }

    do {
        try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default)            
        try AVAudioSession.sharedInstance().setActive(true)

        /* The following line is required for the player to work on iOS 11. Change the file type accordingly*/
        player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)

        /* iOS 10 and earlier require the following line:
        player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileTypeMPEGLayer3) */

        guard let player = player else { return }

        player.play()

    } catch let error {
        print(error.localizedDescription)
    }
}

Make sure to change the name of your tune as well as the extension.
The file needs to be properly imported (Project Build Phases > Copy Bundle Resources). You might want to place it in assets.xcassets for
greater convenience.

For short sound files you might want to go for non-compressed audio formats such as .wav since they have the best quality and a low cpu impact. The higher disk-space consumption should not be a big deal for short sound files. The longer the files are, you might want to go for a compressed format such as .mp3 etc. pp. Check the compatible audio formats of CoreAudio.

Fun-fact: There are neat little libraries which make playing sounds even easier. :)

For example: SwiftySound

Playing system sounds using Swift

I believe the correct way is to use the filetype in the third parameter:

    var soundID: SystemSoundID = 0
    var mainBundle: CFBundleRef = CFBundleGetMainBundle()
    if let ref: CFURLRef = CFBundleCopyResourceURL(mainBundle, CFSTR("roar"), CFSTR("aif"), nil) {
        println("Here is your ref: \(ref)")
        AudioServicesCreateSystemSoundID(ref, &soundID)
        AudioServicesPlaySystemSound(soundID)
    } else {
        println("Could not find sound file")
    }

Are you sure the file is roar.aif and not roar.aiff?

Make sure the file is not in a subdirectory, if so you have to add this as a fourth parameter.
