Thanks @DrXibber for your insights. Do you think it'd be possible to use one of these custom properties to have the app pass around NSData* representing a frame that ultimately gets shown by the Camera Extension? That way we wouldn't need complicated XPC (which nobody seems to have figured out yet except perhaps @ssmith_c in https://developer.apple.com/forums/thread/706184 ?) or even use another sink stream (also suggested by @ssmith_c).
