Is it possible to observe kotlin class properties in swift? Like with ObservableObject and Published in swiftUI.

Yes, inherit ObserableObject and use `Binding`: https://github.com/hfhbd/ComposeTodo/blob/main/iosApp/Shared/ViewModel.swift

And you need to use this StateObject.init: https://github.com/hfhbd/ComposeTodo/blob/a83a90eac6f6e20bb30e6f92e5ba46de9f1a3852/iosApp/Shared/ContentView.swift#L47

Another option is to use https://github.com/rickclephas/KMP-NativeCoroutines and can map Flow/StateFlow in shared code pretty seamlessly to Swift AsyncSequence

[hfhbd]

But with NativeCoroutines you still need a Swift ViewModel to update the values, or SwiftUI.State variables

[John O'Reilly]

yeah, that's true....for me that's worked out ok but I guess it depends on architecture/setup you're using

[John O'Reilly]

In my case I'm consuming StateFlow (as AsyncSequence) from repository (in the Swift ViewModel) and, in some cases anyway, mapping/transforming/combining that before assigning to @Published the property

Thanks for the tip guys!
