ReSwift

Stores the entire app state in a single data structure, simplifying debugging and state tracking, as demonstrated in the counter example where state is a simple struct.

State changes only occur through dispatched actions, ensuring consistency and making mutations explicit, which reduces errors in complex apps.

Reducers are side-effect-free, computing new state based solely on actions and current state, enhancing testability and reliability, as shown in the basic reducer implementation.

Core components work across iOS, macOS, tvOS, and watchOS, enabling shared business logic, mentioned in the platform support section and philosophy.

Supports community extensions like ReSwift-Thunk for async actions and ReSwift-Recorder for time-travel debugging, adding flexibility beyond the core library.
