Question 1

How to debounce user input in Swift with AsyncNinja?

Accepted Answer

Use the `debounce` operator on a reactive property, like `searchBar.rp.text.debounce(interval: 0.3)`, then chain `distinct` and `flatMap` for processing, as demonstrated in the README's search example. This reduces network calls and improves performance.

Question 2

AsyncNinja vs RxSwift: which is better for iOS?

Accepted Answer

AsyncNinja simplifies memory management with automatic context handling, reducing boilerplate, while RxSwift has a larger operator set and community. Choose AsyncNinja for cleaner code with less manual work, or RxSwift for maximum flexibility and extensive resources.

Question 3

How to avoid memory leaks when using AsyncNinja in view controllers?

Accepted Answer

Pass the view controller as a context parameter in methods like `onSuccess` or `map`, which automatically cancels operations when the context is deallocated. This removes the need for [weak self] and manual cleanup, ensuring safe resource management.

Question 4

Does AsyncNinja work with SwiftUI?

Accepted Answer

Yes, but integration may require custom adapters since AsyncNinja's bindings and reactive properties are designed for UIKit/AppKit. You can use it for state management, but it's not as seamless as native SwiftUI tools like Combine publishers.

Question 5

What's the performance cost of using Channels over GCD?

Accepted Answer

Channels add abstraction overhead compared to raw Grand Central Dispatch, but for most apps, the convenience and safety benefits outweigh this. Profile performance-critical sections if needed, as the library optimizes common operations like threading automatically.

Question 6

How to convert callback-based APIs to futures in AsyncNinja?

Accepted Answer

Create a Promise, pass its `complete` method as the callback, and return the Promise as a Future. Example: `func fetch() -> Future { let promise = Promise(); legacyFetch(callback: promise.complete); return promise }`, as shown in the README.
