I recently put together a sample that demonstrates a redux-like store using kotlin flows in a multi-platform project and rendering to SwiftUI views in a unidirectional data flow. It seems to be working great with one exception. State is updated as the flow collects / iterates but the UI never repaints until the flow completes. I'm suspecting it's in the single threaded nature of coroutines on iOS and that I need a newer build of coroutines native-mt. I'm making some assumptions there though. Curious if anyone has any ideas? Here is the project.

You’re using SwiftUI but in Swift, did you try using it in Kotlin? I’m working on a 100% Kotlin iOS app but right now I’m still building iOS views the old way, with just a small DSL I made to help

No, you can't to my knowledge use swift only api's from kotlin. One simple example is that SwiftUI views are structs and currently there is no translation there. I think for me leaning on Swift only for the view with the SwiftUI api is a good compromise, it feels less like programming in swift and more like a view DSL.
I should also add that the live preview of SwiftUI views makes building out screens ridiculously easy and the feedback is very fast.
