Comment jouer un son sur iOS 11 avec Swift 4? Et où je place le fichier mp3?

J’ai vu beaucoup de tutoriels mais quand je clique sur le bouton (qui active le son func), le son ne joue pas J'ai vu le code recommandé par stackoverflow mais rien. J'ai mis l'info de fichier mp3 asset.xcasset. C'est juste?

Swift 4/XCODE 9.1 

import AVFoundation

var objPlayer: AVAudioPlayer?

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

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

        // For iOS 11 
        objPlayer = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)

        // For iOS versions < 11 
        objPlayer = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileTypeMPEGLayer3) 

        guard let aPlayer = objPlayer else { return }
        aPlayer.play()

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

Notez que vous devez appeler AVAudioSession.sharedInstance().setCategory() avec le paramètre mode dans Swift 4.2.

import AVFoundation

var audioPlayer: AVAudioPlayer?

func playSound() {
    if let audioPlayer = audioPlayer, audioPlayer.isPlaying { audioPlayer.stop() }

    guard let soundURL = Bundle.main.url(forResource: "audio_file", withExtension: "wav") else { return }

    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, mode: AVAudioSession.Mode.default)
        try AVAudioSession.sharedInstance().setActive(true)
        audioPlayer = try AVAudioPlayer(contentsOf: soundURL)
        audioPlayer?.play()
    } catch let error {
        Print.detailed(error.localizedDescription)
    }
}

Une solution très simple.

import AVFoundation

var myAudioPlayer = AVAudioPlayer?

func playAudioFile() {

    let audioFileURL = Bundle.main.url(forResource: "<name-of-file>", withExtension: "mp3/wav/m4a etc.")

    do {
        try myAudioPlayer = AVAudioPlayer(contentsOf: audioFileURL!)
    } catch let error {
        print(error.localizedDescription)
    }

    myAudioPlayer?.play()

}

Maintenant, jouez ce fichier audio n'importe où en appelant: playAudioFile()

Ajoutez votre fichier .mp3 à Bundle

import AVFoundation

let url = Bundle.main.url(forResource: "SampleAudio", withExtension: "mp3")

    let playerItem = AVPlayerItem(url: url!)
    let player=AVPlayer(playerItem: playerItem)
    let playerLayer=AVPlayerLayer(player: player)

    playerLayer.frame = CGRect(x: 0, y: 0, width: 0, height: 0)
    self.view.layer.addSublayer(playerLayer)
    player.play()

import AVFoundation

class ViewController: UIViewController {

var timer : Timer?

    time += 5.0

        // stop, track skip or whatever you want
    }
    else
    {
        player?.currentTime = time

Manière simple avec Swift 4.2 :

import AVFoundation

et 

   let soundEffect = URL(fileURLWithPath: Bundle.main.path(forResource: "btn_click_sound", ofType: "mp3")!)
   var audioPlayer = AVAudioPlayer()

   @IBAction func buttonClick(sender: AnyObject) {
       do {
            audioPlayer = try AVAudioPlayer(contentsOf: soundEffect)
            audioPlayer.play()
       } catch {
          // couldn't load file :(
       } 
   }
