So I'm trying to implement a platform-specific class with specific generic types and having some problems doing that, mainly because the expected declaration needs to match the actual type-specific one, which obviously does not work. Here is an example:

// common
interface SomeType

abstract class AbstractTypeWrapper<T: SomeType> {
    protected abstract fun instantiate(): T
}

expect class TypeWrapper : AbstractTypeWrapper<SomeType>
                                              ^^^--- this is obviously different
// android
interface AndroidType: SomeType

actual class TypeWrapper : AbstractTypeWrapper<AndroidType>() {
    override fun instantiate(): AndroidType {
        // ...
    }
}

// desktop
interface DesktopType: SomeType

actual class TypeWrapper : AbstractTypeWrapper<DesktopType>() {
    override fun instantiate(): DesktopType {
        // ...
    }
}

How would I continue here?

Ok, making the supertype expect/actual seems to be the way to go.
