I did archive my tvos app and validate with Xcode7.1Beta, then show below error message.It not yet start to recieve tvos app on appstore?
An error occured. Archive did not contain known itunes platform.
You need to upgrade xcode to 7.1 beta 2, you can then actually upload your tvOS app for testflight testing and to check that it uploads ok.
To submit for the store, you will need the GM as the previous answers says.
