## What it is
RxFeedback is a Swift library providing a universal 'system' operator and architecture for RxSwift, modeling apps as state machines driven by feedback loops. It separates pure reducer logic from side effects declaratively, with compile-time guarantees of no unhandled states.

## Use cases
- build unidirectional data flow architecture in Swift apps
- manage state in RxSwift-based iOS apps
- separate business logic from side effects in reactive apps
- test app state transitions with pure reducer functions
- model complex event-driven UI behavior with feedback loops

## When to choose
- you already use RxSwift and want a simple state management architecture
- you want declarative, testable state machines for iOS/macOS apps
- you need to model circular dependencies or feedback-driven behavior

## When to avoid
- your project uses Combine or async/await instead of RxSwift
- you want a batteries-included framework with UI bindings and middleware ecosystem
- you need a library under active development - releases have been infrequent since 2023
