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?
