AvPlayer is unable to play sound in device - ios

Question

My code perfectly works fine in the simulator and it streams the url without any issue. But when plugged to the actual device it doesnt play the audio. My code as bellow
var playerItem: AVPlayerItem?
var player: AVPlayer?
func initPlayer() {
let url:URL = URL(string:"https://storage.googleapis.com/purelightdatabucket/samples%2F60-Energy%20UPLIFT.mp3")!
self.playerItem = AVPlayerItem(url: url)
self.player=AVPlayer(playerItem: self.playerItem!)
let playerLayer=AVPlayerLayer(player: self.player!)
playerLayer.frame = CGRect(x: 0, y: 0, width: 10, height: 50) // actually this player layer is not visible
self.view.layer.addSublayer(playerLayer)
}

Answer 1

Put this code in didFinishLaunchingWithOptions
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback)
try AVAudioSession.sharedInstance().setActive(true)
} catch {
print(error)
}

Answer 2

you can use this too :
You need to add AVKit & AVFoundation to your frameworks path and import them :
import UIKit
import AVKit
import AVFoundation
class ViewController: UIViewController {
var player = AVPlayer()
override func viewDidLoad() {
super.viewDidLoad()
let playerItem = AVPlayerItem(url: URL(string: "https://storage.googleapis.com/purelightdatabucket/samples%2F60-Energy%20UPLIFT.mp3")!)
player = AVPlayer(playerItem: playerItem)
player.play()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
