@eskimo Has anything changed yet? There is literally no good modern information on installer plugins. Is there a Swift API yet and can we compile, debug a plugin as a Swift package SPM?

Luckily our team (unlike other projects) is not limited to the language and compiler version and I managed over a few months to update our build environment to use C++20. Unfortunately on macOS we are limited by XCode 13. Particularly libc++ is very far behind from what's available in the current Clang.
