Vision Sample for Tracking Rectangles / Objects not working anymore

The following Vision sample for tracking rectangles / objects here -> https://developer.apple.com/documentation/vision/tracking_multiple_objects_or_rectangles_in_video

Doesn't currently work properly in Xcode 11.6.

I don't think anything is specifically wrong with the Vision part but how they are rendering these videos to frame is not working.
