Spin
A Swift library for building unified feedback loops (state machines) that work with RxSwift, ReactiveSwift, and Combine.
What is Spin?
Spin is a Swift library that implements feedback loops, a pattern for building state machines in applications. It solves the problem of managing state consistently across different reactive frameworks (RxSwift, ReactiveSwift, and Combine) and UI technologies (UIKit, AppKit, SwiftUI), especially during transitions like adopting Combine and SwiftUI. By providing a unified syntax, it ensures architectural consistency regardless of the underlying tools.
Swift developers building iOS, macOS, tvOS, or watchOS applications who use or plan to use multiple reactive frameworks (e.g., RxSwift and Combine) or UI technologies (e.g., UIKit and SwiftUI) and need a consistent state management solution.
Developers choose Spin because it offers a single, unified API for feedback loops that works seamlessly with RxSwift, ReactiveSwift, and Combine, eliminating the need to rewrite state management logic when switching frameworks. Its design isolates side effects and promotes pure reducers, making code more predictable and easier to test across mixed codebases.
Overview
Spin aims to provide a versatile Feedback Loop implementation working with the three main reactive frameworks available in the Swift community (RxSwift, ReactiveSwift and Combine)
