tvOS is essentially iOS and doesn't require bitcode (yet) like watchOS. I am looking at adding it soon because Xcode 7 enables it by default. I don't totally appreciate all the possible bitcode problems, but one of the suggestions that apps can be updated for new CPUs without rebuilding doesn't make sense. The IR/bitcode from clang for arm64 and armv7 is different. They would have to make all the ABIs identical first or have LLVM backend do more of the ABI work. -- Dan
