How many compilers does Xcode have?
summary
Claims Xcode contains five compilers and then proves it by inspecting the Xcode bundle and command‑line tools, showing which binaries actually compile code versus which are just driver wrappers. Names the ones found: Apple Clang (C/ObjC/C++), Swift compiler, metal compiler, plus a separate frontend for SwiftPM and a legacy GCC shim, explains how symlinks and drivers inflate counts, runs `xcrun` and `strings` to confirm each compiler emits object code, and concludes with a concrete numbered list.
