I'm running the following version of xcode:
Version 7.2.1 (7C1002)
When I uploaded this build and when I try to submit my tvOS app for review I receive the following error:
"New apps and app updates must be built with the public (GM) versions of Xcode 6 or later, OS X, and tvOS SDK. Don't submit apps built with beta software including beta OS X builds."
I never installed any beta versions of Xcode on this machine. I also successfully submitted a tvOS app last week. Since then I did update Xcode with the automatic updates supplied by Apple.
I'm not sure what to do - I could try building under an older version of Xcode. I'm running the latest as far as I can tell.
