Swift 4

func playSound(soundUrl: String) {
    let sound = URL(fileURLWithPath: soundUrl)
    do {
        let audioPlayer = try AVAudioPlayer(contentsOf: sound)
        audioPlayer.prepareToPlay()
        audioPlayer.play()
    }catch let error {
        print("Error: \(error.localizedDescription)")
    }
}

Create a complete Audio player with a progress bar and other stuff ... swift 5 and Xcode 12.1

var player: AVPlayer?
var playerItem:AVPlayerItem?
fileprivate let seekDuration: Float64 = 10


@IBOutlet weak var labelOverallDuration: UILabel!
@IBOutlet weak var labelCurrentTime: UILabel!
@IBOutlet weak var playbackSlider: UISlider!
@IBOutlet weak var ButtonPlay: UIButton!

//call this mehtod to init audio player 
func initAudioPlayer{
    let url = URL(string: "https://argaamplus.s3.amazonaws.com/eb2fa654-bcf9-41de-829c-4d47c5648352.mp3")
    let playerItem:AVPlayerItem = AVPlayerItem(url: url!)
    player = AVPlayer(playerItem: playerItem)
    
    playbackSlider.minimumValue = 0
    
    //To get overAll duration of the audio
    let duration : CMTime = playerItem.asset.duration
    let seconds : Float64 = CMTimeGetSeconds(duration)
    labelOverallDuration.text = self.stringFromTimeInterval(interval: seconds)
    
    //To get the current duration of the audio
    let currentDuration : CMTime = playerItem.currentTime()
    let currentSeconds : Float64 = CMTimeGetSeconds(currentDuration)
    labelCurrentTime.text = self.stringFromTimeInterval(interval: currentSeconds)
    
    playbackSlider.maximumValue = Float(seconds)
    playbackSlider.isContinuous = true
    
    
    
    player!.addPeriodicTimeObserver(forInterval: CMTimeMakeWithSeconds(1, preferredTimescale: 1), queue: DispatchQueue.main) { (CMTime) -> Void in
        if self.player!.currentItem?.status == .readyToPlay {
            let time : Float64 = CMTimeGetSeconds(self.player!.currentTime());
            self.playbackSlider.value = Float ( time );
            self.labelCurrentTime.text = self.stringFromTimeInterval(interval: time)
        }
        let playbackLikelyToKeepUp = self.player?.currentItem?.isPlaybackLikelyToKeepUp
        if playbackLikelyToKeepUp == false{
            print("IsBuffering")
            self.ButtonPlay.isHidden = true
            //        self.loadingView.isHidden = false
        } else {
            //stop the activity indicator
            print("Buffering completed")
            self.ButtonPlay.isHidden = false
            //        self.loadingView.isHidden = true
        }
    }
   
   //change the progress value
    playbackSlider.addTarget(self, action: #selector(playbackSliderValueChanged(_:)), for: .valueChanged)
    
    //check player has completed playing audio
    NotificationCenter.default.addObserver(self, selector: #selector(self.finishedPlaying(_:)), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: playerItem)}


@objc func playbackSliderValueChanged(_ playbackSlider:UISlider) {
    let seconds : Int64 = Int64(playbackSlider.value)
    let targetTime:CMTime = CMTimeMake(value: seconds, timescale: 1)
    player!.seek(to: targetTime)
    if player!.rate == 0 {
        player?.play()
    }
}

@objc func finishedPlaying( _ myNotification:NSNotification) {
    ButtonPlay.setImage(UIImage(named: "play"), for: UIControl.State.normal)
    //reset player when finish   
    playbackSlider.value = 0
    let targetTime:CMTime = CMTimeMake(value: 0, timescale: 1)
    player!.seek(to: targetTime)
}

@IBAction func playButton(_ sender: Any) {
    print("play Button")
    if player?.rate == 0
    {
        player!.play()
        self.ButtonPlay.isHidden = true
        //        self.loadingView.isHidden = false
        ButtonPlay.setImage(UIImage(systemName: "pause"), for: UIControl.State.normal)
    } else {
        player!.pause()
        ButtonPlay.setImage(UIImage(systemName: "play"), for: UIControl.State.normal)
    }
    
}


func stringFromTimeInterval(interval: TimeInterval) -> String {
    let interval = Int(interval)
    let seconds = interval % 60
    let minutes = (interval / 60) % 60
    let hours = (interval / 3600)
    return String(format: "%02d:%02d:%02d", hours, minutes, seconds)
}



@IBAction func seekBackWards(_ sender: Any) {
    if player == nil { return }
    let playerCurrenTime = CMTimeGetSeconds(player!.currentTime())
    var newTime = playerCurrenTime - seekDuration
    if newTime < 0 { newTime = 0 }
    player?.pause()
    let selectedTime: CMTime = CMTimeMake(value: Int64(newTime * 1000 as Float64), timescale: 1000)
    player?.seek(to: selectedTime)
    player?.play()

}


@IBAction func seekForward(_ sender: Any) {
    if player == nil { return }
    if let duration = player!.currentItem?.duration {
       let playerCurrentTime = CMTimeGetSeconds(player!.currentTime())
       let newTime = playerCurrentTime + seekDuration
       if newTime < CMTimeGetSeconds(duration)
       {
          let selectedTime: CMTime = CMTimeMake(value: Int64(newTime * 1000 as 
       Float64), timescale: 1000)
          player!.seek(to: selectedTime)
       }
       player?.pause()
       player?.play()
      }
}

The end result looks like this ...

Answer 3

After some research, and some disappointment since none of the answers solved my problem, I've come to a solution and here's the final result. The accepted answer is half right, you still need to create an AVPlayerLayer

let url = URL(string: "https://www.myinstants.com/media/sounds/cade-o-respeito.mp3" ?? "")
playerItem = AVPlayerItem(url: url!)
player = AVPlayer(playerItem: playerItem)

let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = CGRect(x: 0, y: 0, width: 10, height: 10)
self.contentView.layoutSublayers(of: playerLayer)

player?.play()

Answer 4

Since AVPlayer is very limited (for example you cannot change url there without regenerate whole AVPlayer I think you should use AVQueuePlayer:

From the docs:

AVQueuePlayer is a subclass of AVPlayer used to play a number of items in sequence. Using this class you can create and manage a queue of player items comprised of local or progressively downloaded file-based media, such as QuickTime movies or MP3 audio files, as well as media served using HTTP Live Streaming.

So in Swift 3 it will work like this:

lazy var playerQueue : AVQueuePlayer = {
    return AVQueuePlayer()
}()

...

func playTrackOrPlaylist{
    if let url = track.streamURL() { //this is an URL fetch from somewhere. In this if you make sure that URL is valid
        let playerItem = AVPlayerItem.init(url: url)
        self.playerQueue.insert(playerItem, after: nil)
        self.playerQueue.play()
    }
}

Answer 5

Use AVPlayer instead of AVAudioPlayer to play remote content. As per documentation AVAudioPlayer needs mp3 file to play Audio. AVAudioPlayer not provide support for streaming.

Try this code , its working fine for me

func play(url:NSURL) {
    print("playing \(url)")

    do {

        let playerItem = AVPlayerItem(URL: url)

        self.player = try AVPlayer(playerItem:playerItem)
        player!.volume = 1.0
        player!.play()
    } catch let error as NSError {
        self.player = nil
        print(error.localizedDescription)
    } catch {
        print("AVAudioPlayer init failed")
    }
}

Please keep in mind to set App Transport Security(ATS) in info.plist file.

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
    </dict>

Answer 6

To play a sound in swift2 is

func playSound(soundUrl: String)
{
   let sound = NSURL(soundUrl)
  do{
      let audioPlayer = try AVAudioPlayer(contentsOfURL: sound)
      audioPlayer.prepareToPlay()
      audioPlayer.play()
  }catch {
      print("Error..")
  }
}

Let me know if it working.
