How do I declare a weak variable with the expect/actual pattern that also becomes a weak variable when used in Swift? I’ve tried

actual var listener: WeakReference<T>? = null

and updated my calls to

listener?.get()?.method()

. But once I use my shared code in Swift, the

listener

variable is not the expected

weak var listener: T

but a wrapped

KotlinWeakReference

. If I use this, it is the same as without – the value assigned to listener, a UIViewController, does not get deallocated once all the references in the concrete implementation are gone (the view controller gets dismissed and should not receive further messages from the listener)

I wrote one for my project. Common was the minimal i needed: expect class WeakRef<T:Any> (referred:T) { fun get(): T? }

Thanks! In the meantime, I solved it using a proxy object in iOS (outside the lib) that holds a weak var to my controller. The proxy objects lifetime depends on the memory management of kotlin, but at least the memory-heavy ViewController gets released once the controller is no longer used.
