This document explains that it is OK to leave TestFlight SDK in a production build for the App Store.
But the TestFlight Live they're talking about turned into a new service called FlightPath, which happens to be in private beta. I applied for it weeks ago and never got access. With this change, can I still make my app future-proof and FlightPath compatible by leaving the TestFlight SDK in the App Store build or should I remove it and wait until I get access to FlightPath?
yes it should be ok .. just don't set the UniqueIdentifier for [TestFlight takeOff:]
