| ## Swift/C++ interoperability is now supported |
| |
| 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][1]. |
| |
| Swift 5.9 is required to use this feature. Xcode 15 is required if the |
| Xcode backend is used. |
| |
| ```meson |
| lib = static_library('mylib', 'mylib.cpp') |
| exe = executable('prog', 'main.swift', 'mylib.h', link_with: lib, swift_interoperability_mode: 'cpp') |
| ``` |
