Objective-C interoperability for KMM

[OndraBasler]

I have a KMM project and I want to create a simple KMM library for Piano analytics. I am facing the issue that I don't see a generated API in Kotlin. The issue is that this library is pure Swift and its public API is not exported to Objective-C. Kotlin/Native can work only with Objective-C. According to the documentation, the easy fix might be to add @objc to all public API classes and functions.

I can create a workaround on my side by creating a Swift library that would expose relevant API to Objective-C in the meantime. However I believe that the simplest solution to add the annotations to this library. This change would open doors to creating the KMM library that can be used by everyone.

I created a sample KMM library where you can see that the API is not generated. There isn't the workaround for the current state
