The Swift community maintains a version which adds support for the language. It is known to work on macOS , Linux , FreeBSD , and Windows , [3] and supports i386 , x86-64 , and ARM instruction sets [4] . If you intend to use Clang's C++ support, you may need to tell it how to find your C++ standard library headers. In general, Clang will detect the best version of libstdc++ headers available and use them - it will look both for system installations of libstdc++ as well as installations adjacent to Clang itself.
