Questions tagged [bitcode]

An intermediate representation of an LLVM-compiled program, which can be used by Apple to optimize binaries submitted to their App Store(s) without requiring involvement from the original developer.

Coming to general attention during WWDC 2015, Bitcode is according to Apple's docs:
