## What it is
ReSwift is a Redux-inspired Swift library implementing unidirectional data flow architecture. It centralizes app state in a single store, mutated only via dispatched actions handled by reducers, with views automatically updating on state changes.

## Use cases
- manage app state in an iOS app with unidirectional data flow
- implement Redux-style architecture in Swift
- make SwiftUI or UIKit views reflect a single source of truth
- debug app state changes predictably with actions and reducers
- coordinate state across many collaborators on a large Swift codebase

## When to choose
- you're building an iOS, macOS, tvOS, or watchOS app and want Redux-like predictable state management
- your team struggles with scattered, hard-to-debug mutable state
- you want a tiny, readable library you can fully understand and extend

## When to avoid
- you're not developing in Swift or targeting Apple platforms
- your app is small enough that a simple architecture suffices and Redux boilerplate adds overhead
- you need a framework with first-class SwiftUI bindings or active feature development

## Facets
- artifact type: library
- maturity: maintenance
- function: state-management, ui-components
- domain: mobile-development, frontend, web-development
- platform: cross-platform
- tags: redux, unidirectional-data-flow, swift, architecture-pattern, apple-platforms, ios, macos
