Is there a way to emit C/C++ header?

Using Swift

Quoting Setting Up Mixed-Language Swift and C++ Projects from swift.org:

The -emit-clang-header-path Swift frontend flag can be used to emit a generated header when exposing Swift APIs to C++ when building Swift code in a build system that doesn’t provide automatic support for generating a header file with exposed APIs.

The following Swift compiler invocation emits a generated header file for the SwiftModule module that consists of two source files, a.swift and b.swift:

swiftc -frontend -typecheck \
       /sources/a.swift /sources/b.swift -module-name SwiftModule \
       -cxx-interoperability-mode=default \
       -emit-clang-header-path SwiftModule-Swift.h

I haven’t tried this.
