Using Xcode Version 7.1 beta (7B75) I get "Failed to render and update autolayout status for ViewController"
Steps
1) Open new File => TVOS Application => Tabbed Application
2) Build Application
3) 3 errors
Failed to render and update autolayout status for FirstViewController.. IBAppleTVSimulatorAgent.app(22023) failed to launch
Failed to render and update autolayout status for SecondViewController... IBAppleTVSimulatorAgent.app(22023) failed to launch
Failed to render and update autolayout status for UITabBarViewController.. IBAppleTVSimulatorAgent.app(22023) failed to launch
No changes made to application. Attempting to build it on AppleTV Schema rather than simulator
