Hey. I am trying to create a present view with a bunch of media (images/videos). Right now I am using a ZStack to render each media and change opacity based on the index selected using a scrollView. The issue seems to be that sometimes, videos don't seem to load in the main slide. There is a slide created as the video exists, the Player shows controls too but doesn't play anything. Present View Z-Stack ZStack { ForEach(presentation.slides.indices, id: .self) { index in if let media = mediaCacheManager.mediaCache[index] { if let player = media as? AVPlayer { PlayerView(player: player) .aspectRatio(16/10, contentMode: .fit ) .frame(width: UIScreen.main.bounds.width * 0.8) .background(Color.gray.opacity(0.2)) .clipShape(RoundedRectangle(cornerRadius: 40)) .overlay( RoundedRectangle(cornerRadius: 40) .stroke(Color.gray.opacity(0.5), lineWidth: 1) ) .onDisappear { player.pause() } .opacity(appModel.currentSlide == index ? 1 : 0) } else if let image = media as? Image { image .resizable() .scaledToFit() .frame(width: UIScreen.main.bounds.width * 0.8) .background(Color.gray.opacity(0.2)) .clipShape(RoundedRectangle(cornerRadius: 40)) .overlay( RoundedRectangle(cornerRadius: 40) .stroke(Color.gray.opacity(0.5), lineWidth: 1) ) .padding(.vertical, 10) .opacity(appModel.currentSlide == index ? 1 : 0) } } } } The PlayerView public class PlayerUIView: UIView { let playerVC = AVPlayerViewController() let gravity: AVLayerVideoGravity let manageAudio: Bool override init(frame: CGRect) { self.gravity = .resizeAspectFill self.manageAudio = true super.init(frame: frame) } deinit { if manageAudio { try? AVAudioSession.sharedInstance().setActive(false) } } init(player: AVPlayer?, gravity: AVLayerVideoGravity, manageAudio: Bool = true) { self.gravity = gravity self.manageAudio = manageAudio super.init(frame: .zero) guard let player = player else { return } self.playerSetup(player: player) } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } public override func layoutSubviews() { super.layoutSubviews() playerVC.view.frame = bounds playerVC.view.backgroundColor = .clear playerVC.allowsVideoFrameAnalysis = false } private func playerSetup(player: AVPlayer) { playerVC.updatesNowPlayingInfoCenter = true playerVC.player = player playerVC.showsPlaybackControls = true playerVC.view.backgroundColor = .clear playerVC.exitsFullScreenWhenPlaybackEnds = true playerVC.videoGravity = gravity self.addSubview(playerVC.view) } }
