Is it possible to use a pure Swift Library for Kotlin Native using cinterop?

I know that as is, that is that possible, but is there any way or work around that I could do to make this work?

Only saw something like this:

(Haven’t tried it on my own)

hi @Oleg Yukhnevich Thanks for sharing. By any chance have you tried doing the same?

[Oleg Yukhnevich]

Nope, but have plans for try it near future (not required at the moment)

I looked into the project looks like it is a prerequesite that the library is annotated with public and @objc . Looks like the same way that native.cocoapods work.

[Oleg Yukhnevich]

AFAIK the idea is to create your own mini-library in Swift with public + @objc which under the hood will use other Swift library (which you want to use)

I’ll try and experiment on this as well. Looks like I have to wrap the swift library into my own library that would support cinterop (through public + @objc ).

We've just done this at work by creating an ObjC wrapper library.
For a Swift API of moderate complexity; you'll be encountering not only the simple case of applying @objc annotation to 'pass through' functions, but also re-modelling Swift `enum`s as ObjC class structures, where these might be used to express data going to/from the API.
It's leg-work, but overall not too challenging.
