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 (

>Copy Bundle Resources
). You might want to place it inassets.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. 🙂
