ios – This video is unavilable | Error code: 152 – 4

When trying to show youtube video in my app with embeded way, it shows the error code: 152 – 4.
I just want to make a view where passing the YouTube ID will play the YouTube video inside my app’s specific screens/views. Now this error occurs when trying to play the video.

Any workaround on this? I can not find any so far.

My code:

final class YouTubePlayerViewController: UIViewController, WKNavigationDelegate {

    var youtubeId: String
    private var webView: WKWebView!

    init(youtubeId: String) {
        self.youtubeId = youtubeId
        super.init(nibName: nil, bundle: nil)
    }

    required init?(coder: NSCoder) { fatalError() }

    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .black
        setupWebView()
        loadPlayer()
    }

    private func setupWebView() {
        let config = WKWebViewConfiguration()
        config.allowsInlineMediaPlayback = true
        config.allowsAirPlayForMediaPlayback = true
        config.allowsPictureInPictureMediaPlayback = true
        config.mediaTypesRequiringUserActionForPlayback = []

        // Required — tells WKWebView it is allowed to autoplay / inline play
        let prefs = WKWebpagePreferences()
        prefs.allowsContentJavaScript = true
        config.defaultWebpagePreferences = prefs

        webView = WKWebView(frame: view.bounds, configuration: config)
        webView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        webView.navigationDelegate = self
        webView.scrollView.isScrollEnabled = false
        webView.scrollView.bounces = false
        webView.backgroundColor = .black
        webView.isOpaque = true
        view.addSubview(webView)
    }

    func loadPlayer() {
        // The critical trick: we load a real youtube.com URL as the *base*
        // and inject an autoplay embed via HTML. Because the base URL is
        // genuinely youtube.com, WKWebView passes YouTube's origin check.
        let html = """
        
        
          
            
            
          
          
            https://www.youtube.com/watch?v=\(youtubeId)
            
          
        
        """

        // baseURL MUST be a real youtube.com origin — this is what fixes Error 152
        webView.loadHTMLString(html, baseURL: URL(string: "
    }

    func updateYoutubeId(_ newId: String) {
        guard newId != youtubeId else { return }
        youtubeId = newId
        loadPlayer()
    }
}
