swift - TestFlight: No SKSpriteNodes -

i try test spritekit game in testflight. when install build via testflight app shows gray screen admob banner have integrated in storyboard. seems whole gamescene not loaded. installing directly cable works fine.

could related fact have deleted gamescene.sks file?

i error message times:

i using xcode 6.3 , swift 1.2

okay, solved problem. problem was, deleted gamescene.sks file. restored file works.
