Question 1

Is RxAutomaton still maintained or should I use something else?

Accepted Answer

No, RxAutomaton is discontinued and not maintained. The author recommends switching to Actomaton for similar functionality, so it's not suitable for new projects needing long-term support.

Question 2

How to handle async API calls with RxAutomaton?

Accepted Answer

Define effects as RxSwift Observables in the mappings, like loginOKProducer in the README example. These Observables can perform API calls and automatically send inputs back to transition states, keeping side effects isolated.

Question 3

RxAutomaton vs Redux for iOS apps: which is better?

Accepted Answer

RxAutomaton is tailored for RxSwift with a state machine approach and built-in effect handling, while Redux is more generic and often requires middleware for async actions. Choose RxAutomaton if you're deep in RxSwift; otherwise, consider Redux with Swift-friendly implementations.

Question 4

Can I use RxAutomaton with SwiftUI and Combine?

Accepted Answer

Technically yes, but it's not ideal because RxAutomaton depends on RxSwift, requiring bridging to Combine or SwiftUI. This adds complexity, and native Combine-based solutions are better suited for SwiftUI projects.

Question 5

What are good alternatives to RxAutomaton for state management?

Accepted Answer

For RxSwift users, Actomaton is the direct successor. For SwiftUI, consider Combine-driven libraries like The Composable Architecture (TCA) or ReSwift, which offer similar declarative patterns without RxSwift dependency.

Question 6

How to test state transitions in RxAutomaton?

Accepted Answer

Leverage the state and reply Observables to subscribe and assert expected values. The declarative mappings allow you to mock effects and inputs, making it easy to unit test transition logic in isolation.
