Will iOS 14 picture-in-picture be available to 3rd party VoIP apps? So that it can work like the FaceTime demo where user can see video feed of remote user in a Picture-in-Picture window. If yes, any official documentation on how to enable it?
iOS 14 Picture-in-Picture for VoIP app
My gut feeling is it won't be available for 3rd party VoIP apps for now. Apple has the tradition to gain unfair advantages on FaceTime within their closed ecosystem.
