Question 1

How do I handle errors in ReactiveKit signals?

Accepted Answer

ReactiveKit provides operators like `retry`, `recover`, and `suppressError` to manage errors. Signals can be converted to safe types using `Never` for bindings, as shown in the error handling section of the README.

Question 2

ReactiveKit vs Combine: which should I use?

Accepted Answer

ReactiveKit is a lightweight, cross-platform alternative with a simpler learning curve, while Combine is Apple's native framework with deeper iOS/macOS integration. ReactiveKit is aligning its API with Combine but isn't a drop-in replacement, so choose based on platform needs and familiarity.

Question 3

How to bind a signal to a UI element in ReactiveKit?

Accepted Answer

Use the `bind(to:keyPath:)` method for non-failable signals, or integrate with the Bond framework for reactive extensions. The README explains bindings require safe signals and proper execution contexts for threading.

Question 4

What are subjects and when should I use them?

Accepted Answer

Subjects like `PassthroughSubject` and `ReplaySubject` bridge imperative code to reactive signals by allowing manual event sending. They're useful for converting actions, such as button taps, into observable sequences, as detailed in the README.

Question 5

Can ReactiveKit be used with SwiftUI?

Accepted Answer

Yes, but SwiftUI uses Combine natively, so you may need to bridge signals between ReactiveKit and Combine for interoperability. ReactiveKit's cross-platform support makes it suitable for shared Swift codebases.

Question 6

How to share event sequences across multiple observers?

Accepted Answer

Use the `shareReplay(limit:)` operator to ensure all observers see the same sequence and avoid redundant event production. The README explains this with subjects and connectable signals for efficient sharing.

Question 7

Is ReactiveKit good for server-side Swift projects?

Accepted Answer

Yes, its Linux compatibility makes it suitable for server-side Swift applications, as noted in the cross-platform support. It handles asynchronous events and data streams declaratively, useful for backend logic.
