It is now possible to create Swift executables that can link to C++ or Objective-C++ libraries. To enable this feature, set the target kwarg swift_interoperability_mode to ‘cpp’.
To import C++ code, specify a bridging header in the Swift target's sources, or use another way such as adding a directory containing a Clang module map to its include path.
Note: Enabling C++ interoperability in a library target is a breaking change. Swift libraries that enable it need their consumers to enable it as well, as per the Swift documentation.
Swift 5.9 is required to use this feature. Xcode 15 is required if the Xcode backend is used.
lib = static_library('mylib', 'mylib.cpp') exe = executable('prog', 'main.swift', 'mylib.h', link_with: lib, swift_interoperability_mode: 'cpp')
