Is there any way to interface with Objective C’s KVO system in Kotlin Native without writing Objective C / Swift?

I’ve been able to add and remove observers in Kotlin, but I haven’t found a way to actually listen to changes. observeValueForKeyPath does exist on NSObject, but I can’t really do much with it because it’s an extension function.

we expose it as a Flow in our kaluga library, it’s not so well documented since we mostly just use it inside the library itself:

example of a simple test:
