When compiling to native binary (.so, framework, ....

When compiling to native binary (.so, framework, ...), is there any way to filter out some public symbols so they won't be exposed? Maybe an annotation?

Thanks Artem, that works for Apple. Is there anything else for other platforms?

I believe no 😔 Is there a reason why you can’t make them internal?

It’s pretty simple, I have a project with many modules which are combined into a single binary. So I need public to make stuff accessible to sibling modules, but I need a bit more control over symbols that are actually exposed by the binary to the end user.

If you think it’s a valid use case, I could file a ticket.

Also if you can think of any workaround, please let me know! I’m open to write a compiler plugin if it helps.

The obvious workaround is to proxy all the library API in the “umbrella” module and export only it. It seems robust but can be cumbersome. But the case is pretty valid nevertheless IMHO.

What about an opt-in annotation? https://kotlinlang.org/docs/opt-in-requirements.html
