Je voudrais jouer un son avec Swift.

Mon code fonctionnait dans Swift 1.0 mais maintenant il ne fonctionne plus dans Swift 2 ou plus récent.

override func viewDidLoad() {
  super.viewDidLoad()

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

  do { 
    player = try AVAudioPlayer(contentsOfURL: url, fileTypeHint: nil) 
  } catch _{
    return
  }

  bgMusic.numberOfLoops = 1
  bgMusic.prepareToPlay()

  if (Data.backgroundMenuPlayed == 0){
    player.play()
    Data.backgroundMenuPlayed = 1
  }
}

De préférence, vous pouvez utiliser AVFoundation . Il fournit tous les éléments essentiels pour travailler avec les médias audiovisuels.

Mise à jour: Compatible avec Swift 2 , Swift 3 et Swift 4 comme suggéré par certains d'entre vous dans les commentaires.

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 (compatible iOS 13)

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)
    }
}

Assurez-vous de changer le nom de votre morceau ainsi que l' extension . Le fichier doit être correctement importé ( Project Build Phases> Copy Bundle Resources). Vous voudrez peut-être le placer assets.xcassetspour plus de commodité.

Pour les fichiers son courts, vous voudrez peut-être opter pour des formats audio non compressés, par exemple, .wavcar ils ont la meilleure qualité et un faible impact sur le processeur. La consommation d'espace disque plus élevée ne devrait pas être un problème pour les fichiers son courts. Plus les fichiers sont longs, vous voudrez peut-être opter pour un format compressé tel que .mp3etc. pp. Vérifiez les formats audio compatibles de CoreAudio.

Fait amusant: il existe de jolies petites bibliothèques qui facilitent encore plus la lecture des sons. :)
Par exemple: SwiftySound

Pour Swift 3 :

import AVFoundation

/// **must** define instance variable outside, because .play() will deallocate AVAudioPlayer 
/// immediately and you won't hear a thing
var player: AVAudioPlayer?

func playSound() {
    guard let url = Bundle.main.url(forResource: "soundName", withExtension: "mp3") else {
        print("url not found")
        return
    }

    do {
        /// this codes for making this app ready to takeover the device audio
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        try AVAudioSession.sharedInstance().setActive(true)

        /// change fileTypeHint according to the type of your audio file (you can omit this)

        player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileTypeMPEGLayer3)

        // no need for prepareToPlay because prepareToPlay is happen automatically when calling play()
        player!.play()
    } catch let error as NSError {
        print("error: \(error.localizedDescription)")
    }
}

La meilleure pratique pour les actifs locaux est de le mettre à l'intérieur assets.xcassetset de charger le fichier comme ceci:

func playSound() {
    guard let url = Bundle.main.url(forResource: "soundName", withExtension: "mp3") else {
        print("url not found")
        return
    }

    do {
        /// this codes for making this app ready to takeover the device audio
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        try AVAudioSession.sharedInstance().setActive(true)

        /// change fileTypeHint according to the type of your audio file (you can omit this)

        /// for iOS 11 onward, use :
        player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)

        /// else :
        /// player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileTypeMPEGLayer3)

        // no need for prepareToPlay because prepareToPlay is happen automatically when calling play()
        player!.play()
    } catch let error as NSError {
        print("error: \(error.localizedDescription)")
    }
}

iOS 12 - Xcode 10 bêta 6 - Swift 4.2

Utilisez juste 1 IBAction et pointez tous les boutons sur cette 1 action.

import AVFoundation

var player = AVAudioPlayer()

@IBAction func notePressed(_ sender: UIButton) {
    print(sender.tag) // testing button pressed tag
    let path = Bundle.main.path(forResource: "note\(sender.tag)", ofType : "wav")!
    let url = URL(fileURLWithPath : path)
    do {
        player = try AVAudioPlayer(contentsOf: url)
        player.play()
    } catch {
        print ("There is an issue with this code!")
    }
}

Si le code ne génère aucune erreur, mais que vous n'entendez pas de son, créez le lecteur comme une instance:

   static var player: AVAudioPlayer!

Pour moi, la première solution a fonctionné lorsque j'ai fait ce changement :)

Swift 4, 4.2 et 5

Lire l'audio depuis l'URL et depuis votre projet (fichier local)

import UIKit
import AVFoundation

class ViewController: UIViewController{

var audioPlayer : AVPlayer!

override func viewDidLoad() {
        super.viewDidLoad()
// call what ever function you want.
    }

    private func playAudioFromURL() {
        guard let url = URL(string: "https://geekanddummy.com/wp-content/uploads/2014/01/coin-spin-light.mp3") else {
            print("error to get the mp3 file")
            return
        }
        do {
            audioPlayer = try AVPlayer(url: url as URL)
        } catch {
            print("audio file error")
        }
        audioPlayer?.play()
    }

    private func playAudioFromProject() {
        guard let url = Bundle.main.url(forResource: "azanMakkah2016", withExtension: "mp3") else {
            print("error to get the mp3 file")
            return
        }

        do {
            audioPlayer = try AVPlayer(url: url)
        } catch {
            print("audio file error")
        }
        audioPlayer?.play()
    }

}

Swift 3

import AVFoundation


var myAudio: AVAudioPlayer!

    let path = Bundle.main.path(forResource: "example", ofType: "mp3")!
    let url = URL(fileURLWithPath: path)
do {
    let sound = try AVAudioPlayer(contentsOf: url)
    myAudio = sound
    sound.play()
} catch {
    // 
}

//If you want to stop the sound, you should use its stop()method.if you try to stop a sound that doesn't exist your app will crash, so it's best to check that it exists.

if myAudio != nil {
    myAudio.stop()
    myAudio = nil
}

Importez d'abord ces bibliothèques

import AVFoundation

import AudioToolbox    

définir le délégué comme ceci

   AVAudioPlayerDelegate

écrivez ce joli code sur l'action de bouton ou quelque chose d'action:

guard let url = Bundle.main.url(forResource: "ring", withExtension: "mp3") else { return }
    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        try AVAudioSession.sharedInstance().setActive(true)
        player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)
        guard let player = player else { return }

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

Il s'agit d'un code de base pour rechercher et lire un fichier audio dans Swift.

Ajoutez votre fichier audio à votre Xcode et ajoutez le code ci-dessous.

class ViewController: UIViewController {

   var audioPlayer = AVAudioPlayer() // declare globally

   override func viewDidLoad() {
        super.viewDidLoad()

        guard let sound = Bundle.main.path(forResource: "audiofilename", ofType: "mp3") else {
            print("Error getting the mp3 file from the main bundle.")

        } catch {
            print("Audio file error.")
        }
        audioPlayer.play()
    }

    @IBAction func notePressed(_ sender: UIButton) { // Button action
        audioPlayer.stop()
    }

        // to stop the spound .stop()
    }catch{
        print ("file could not be loaded or other error!")
    }
}

fonctionne dans la dernière version de swift 4. ButtonTag serait une balise sur un bouton de votre interface. Les notes sont dans un dossier dans un dossier parallèle à Main.storyboard. Chaque note est nommée note1, note2, etc. ButtonTag donne le numéro 1, 2, etc. à partir du bouton cliqué qui est passé en paramètre
