Answer 1

SWIFT 4

1 - import AVFoundation

2 - declare player

var player : AVPlayer?

3 - in ViewDidLoad call function and pass the streaming url like String

loadRadio(radioURL: (radioStation?.streamURL)!)

4 - function to play

func loadRadio(radioURL: String) {

        guard let url = URL.init(string: radioURL) else { return }
        let playerItem = AVPlayerItem.init(url: url)
        player = AVPlayer.init(playerItem: playerItem)
        player?.play()
        startNowPlayingAnimation(true)
        played = true
    }

For me is the best and simply way to streaming audio in swift.

Answer 2

I tried the following,

let urlstring = "http://radio.spainmedia.es/wp-content/uploads/2015/12/tailtoddle_lo4.mp3"
let url = NSURL(string: urlstring)
print("the url = \(url!)")
downloadFileFromURL(url!)

Add the below methods,

func downloadFileFromURL(url:NSURL){

    var downloadTask:NSURLSessionDownloadTask
    downloadTask = NSURLSession.sharedSession().downloadTaskWithURL(url, completionHandler: { [weak self](URL, response, error) -> Void in
        self?.play(URL)
    })
        
    downloadTask.resume()
    
}

And your play method as it is,

func play(url:NSURL) {
    print("playing \(url)")
    
    do {
        self.player = try AVAudioPlayer(contentsOfURL: url)
        player.prepareToPlay()
        player.volume = 1.0
        player.play()
    } catch let error as NSError {
        //self.player = nil
        print(error.localizedDescription)
    } catch {
        print("AVAudioPlayer init failed")
    }
    
}

Download the mp3 file and then try to play it, somehow AVAudioPlayer does not download your mp3 file for you. I am able to download the audio file and player plays it.

Remember to add this in your info.plist since you are loading from a http source and you need the below to be set for iOS 9+

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

var player : AVPlayer?
func playSound()
    {
      guard  let url = URL(string: "https://file-examples.com/wp-content/uploads/2017/11/file_example_MP3_700KB.mp3")
     else 
        {
          print("error to get the mp3 file")
          return
        }
     do{
         try AVAudioSession.sharedInstance().setCategory(.playback, mode.default)
         try AVAudioSession.sharedInstance().setActive(true)
         player = try AVPlayer(url: url as URL)
         guard let player = player
               else 
                   { 
                     return 
                   }
         player.play()
      } catch let error {
            print(error.localizedDescription)
               }
   }
