I would like to introduce you to Khipu, an architecture of mine. I started it as a Clean Architecture implementation, but has similarities to flux/redux too.

it is truly UI-independent and can be easily used with SwiftUI and UIKit. I would describe it boilerplate-code-free, as no presenter/router/coordinater/… is needed.
