Hi everyone, did anyone have experience about how create a function like this that could work in the same way on swift?

class GenericClass<T> {
    fun <A> clone(block: (GenericClass<T>) -> GenericClass<A>): GenericClass<A>{
        return block(this)
    }
}

Because currently the compiler generates this implementation that not fill my requirements because the return type is GenericClass<`AnyObject`> instead of be generic <A>

public class GenericClass<T> : KotlinBase where T : AnyObject {
    public init()

    open func clone(block: @escaping (GenericClass<T>) -> GenericClass<AnyObject>) -> GenericClass<AnyObject>
}

Is this implementation wrong? There is a proper way to do that? Thank you!

Well there is nothing wrong with your implementation 🙂.
The reason you are getting AnyObject instead of the generic A is because ObjC doesn't support generics on functions.

Thank you Rick 🙏
