To render webview in ARKit

While this functionality may have worked in some capacity previously with UIWebView (or other UIViews), that behavior was never actually supported. Therefore, I recommend that you file an enhancement request using Feedback Assistant for the specific functionality that you would like.

You may also want to consider displaying your web view in screen space instead (see https://developer.apple.com/documentation/arkit/creating_screen_annotations_for_objects_in_an_ar_experience), as recommended in the HIG (https://developer.apple.com/design/human-interface-guidelines/ios/system-capabilities/augmented-reality/)

Thanks!
