is there any pattern for faking Kotlin classes exposed to Swift?

Let's say I have LoadUserUseCase in my Kotlin shared code.

In Swift i have a UserViewModel which has the usecase injected. Now i want to write tests for this ViewModel, so I need to create a fake. But there is no protocol to conform to and of course Cannot inherit from non-open class 'LoadUserUseCase' outside of its defining module

Make LoadUserUseCase an interface instead of a class. It will translate to Swift as a protocol you can implement.

ha, I just started to do that, but didn;t know if it would work, thank you!
