I really like the approach explained in this repo, however, there's one thing I don't have an satisfactory/convincing answer: Where to mutate AppState.
I often mutate it in an interactor implicitly, thinking whether it is a right thing or not. I'm even not sure passing AppState to interactor is acceptable move.

One thing come to mind is, given that SwiftUI.View is not UIView nor UIViewController but more like a place to declare UI and data flow, a View is the right place?

What do you think, in this repo's context?
I know this kind of discussion has no "Answer", but would like to hear the approaches of professionals around the world.
