I want to take a screenshot with WKWebView contains a playing video. I tried many ways, it works well in Simulator, but on device the video's content is not captured. Simulator: Device: I tried the following ways: CALayer#render let window = UIApplication.shared.windows.first { $0.isKeyWindow } if window == nil { return } let layer = window!.layer let screenRect = window!.screen.bounds UIGraphicsBeginImageContext(screenRect.size) let ctx:CGContext = UIGraphicsGetCurrentContext()! layer.render(in: ctx) self.screenShotImage = UIGraphicsGetImageFromCurrentImageContext() UIGraphicsEndImageContext() and UIView#drawHierarchy let window = UIApplication.shared.windows.first { $0.isKeyWindow } if window == nil { return } UIGraphicsBeginImageContextWithOptions(window!.frame.size, false, 0) window!.drawHierarchy(in: window!.frame, afterScreenUpdates: true) self.screenShotImage = UIGraphicsGetImageFromCurrentImageContext() UIGraphicsEndImageContext() and WKWebView#takeSnapshot let config = WKSnapshotConfiguration() config.rect = WKWebViewHolder.webView!.frame config.afterScreenUpdates = false webView.takeSnapshot(with: config, completionHandler: { (image: UIImage?, error: Error?) in      if error != nil {        return      }      self.screenShotImage = image }) What should I do? 🤔
