How do I xcodebuild a static library with Bitcode enabled?

Question

Xcode 7 introduces Bitcode, which is some sort of LLVM intermediate binary that means Apple\'s servers can recompile my app for different architectures without my involvemen

Answer 1

Once you add bitcode support for the static lib, it won't be compatible with Xcode 6. The app won't archive.

I would like to clearly mention the setting for bitcode as @nevyn's answer confused me a little.

Go to Build settings, search for "custom compiler flags". Add -fembed-bitcode. This will build your lib with bitcode.
