I have same issue. This is my test code.
import AVFoundation
import UIKit
final class ViewController: UIViewController {
	/* view customed to PlayerView */
@IBOutlet var playerView: PlayerView!
override func viewDidLoad() {
super.viewDidLoad()
do {
try AVAudioSession.sharedInstance().setCategory(.playback)
try AVAudioSession.sharedInstance().setActive(true)
} catch {
print(error)
}
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
self.playerView.player?.play()
}
}
final class PlayerView: UIView {
private var player: AVPlayer?
private var playerLayer: AVPlayerLayer {
self.layer as! AVPlayerLayer
}
override static var layerClass: AnyClass {
AVPlayerLayer.self
}
required init?(coder: NSCoder) {
super.init(coder: coder)
self.addNotificationObserver()
self.setupPlayer()
}
func play() {
self.player?.play()
}
private func setupPlayer() {
guard let url = URL(string: "https://devstreaming-cdn.apple.com/videos/streaming/examples/bipbop_4x3/gear1/prog_index.m3u8")
else { return }
self.player = AVPlayer(url: url)
self.playerLayer.player = self.player
}
}
extension PlayerView {
private func addNotificationObserver() {
NotificationCenter.default.addObserver(
self,
selector: #selector(willEnterForeground(_:)),
name: UIApplication.willEnterForegroundNotification,
object: nil
)
NotificationCenter.default.addObserver(
self,
selector: #selector(didEnterBackground(_:)),
name: UIApplication.didEnterBackgroundNotification,
object: nil
)
}
@objc
private func willEnterForeground(_ notification: Notification) {
self.playerLayer.player = self.player
}
@objc
private func didEnterBackground(_ notification: Notification) {
self.playerLayer.player = nil
}
}
