Xcode 11 Beta Simulator-视频播放器-该视频正在电视上播放

Question

我正在尝试使用AVPlayerViewController播放视频，但是模拟器无法显示视频图片。音频工作正常。

模拟器显示：已连接电视-此视频在电视上播放。

这是我的代码：

AppDelegate.swift

import UIKit
import AVFoundation

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.

        let audioSession = AVAudioSession.sharedInstance()
        do {
            try audioSession.setCategory(.playback, mode: .moviePlayback)
        }
        catch {
            print("Setting category to AVAudioSessionCategoryPlayback failed.")
        }
        return true
    }

} 

ViewController.swift

import UIKit
import AVKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }

    @IBAction func playVideo(_ sender: UIButton) {
        guard let url = URL(string: "https://devstreaming-cdn.apple.com/videos/streaming/examples/bipbop_adv_example_hevc/master.m3u8") else {
            return
        }
        // Create an AVPlayer, passing it the HTTP Live Streaming URL.
        let player = AVPlayer(url: url)

        // Create a new AVPlayerViewController and pass it a reference to the player.
        let controller = AVPlayerViewController()
        controller.player = player

        // Modally present the player and call the player's play() method when complete.
        present(controller, animated: true) {
            player.play()
        }
    }
}

结果：
