Answer 1

It's a bug in ios13.0. While presentingVC, ReplayKit use UIApplicationRotationFollowingController(modalTransitionStyle = pageSheet) to present a RPBroadcastPickerStandaloneViewController(modalTransitionStyle = curl). But curl is only available while the previous vc is fullScreen. So the solution is to hook presentApi and change the style.
