How to play mp3 audio from URL in ios swift

Question

I am getting mp3 url as a response of api calling. I want to play that audio, so how can i do that? (ios swift)

here is my response

 {
    content = "En este primer programa se tratar\U00e1n asuntos tan importante como este y aquel sin descuidar un poco de todo lo dem\U00e1s";
    file = "http://radio.spainmedia.es/wp-content/uploads/2015/12/ogilvy.mp3";
    image = "http://radio.spainmedia.es/wp-content/uploads/2015/12/tapas.jpg";
    number = 0001;
    subtitle = Titulareando;
    title = "Tapa 1";
}

here is my code::

 @IBAction func btnplayaudio(sender: AnyObject) {
    let urlstring = "http://radio.spainmedia.es/wp-content/uploads/2015/12/tailtoddle_lo4.mp3"
    let url = NSURL(string: urlstring)
    print("the url = \(url!)")

    play(url!)

}

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")
    }

}

where am i going wrong?

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>
