A modern programming language that makes developers happier.

Can someone explain me something? I am using Kotlin on iOS and trying to implement an MVP architecture. I use a `WeakReference` to hold a reference to a View object from Kotlin, to try and avoid memory leaks. But these objects do not seem to get deallocated immediately when they go out of scope. This is annoying for me as I use iOS `UIViewController` as the view object, and the expectation is that these will have `deinit` called as soon as they are dismissed.

I have tried the project `icerockdev/moko-mvvm`. In their iOS sample project `sample6`, the memory leak does not seem to occur, and the view has `deinit` invoked immediately. I have read the `moko-mvvm` source code and I think their implementation is the same as mine. I can’t understand this.

You can manually set that reference to `nil` in Swift when your `ViewController` calls `deinit` if that’s a concern for you.

The ViewController’s `deinit` is never called because my Kotlin class is clinging on to a reference to it.

Perhaps it's working as expected?  <https://github.com/JetBrains/kotlin-native/issues/3437>.  Do your VCs eventually get deallocated, or did you verify you actually had a memory leak?
