Hi,

Ive managed to build my game using the latest Xcode and run on a device using IOS 9.1 (iPhone 4S). Does than mean its fully compiled for 64bit and compatible for the app store?

Thanks in advance!

Is the Scripting Backend in the Player Settings set to IL2CPP?

If yes, is the Architecture below it set to either ARM64 or Universal?
