My app uses PushKit. When I create a build with Xcode 9 beta 5 PushKit is not working anymore, neither on a iOS 10 nor on a iOS 11 device. The didUpdatePushCredentials and didReceiveIncomingPushWithPayload methods never get called. Also the VoIP setting in Xcode "Capabilities", "Background Modes" is gone. Is this a known beta 5 issue or do I have to enable it elsewhere?
I also get this message, so I think PushKit should be working in order to have an alternative to the setKeepAliveTimeout method: The UIApplication method -[UIApplication setKeepAliveTimeout:handler:] is deprecated and no longer supported. Please use PushKit for VoIP applications instead of calling this method
