Question 1

How to install RWPromiseKit in my Xcode project?

Accepted Answer

Install via Cocoapods by adding 'pod \'RWPromiseKit\', \'0.2.0\'' to your Podfile, or manually copy source files from the 'Class' directory, as specified in the README's Installation section.

Question 2

Does RWPromiseKit support async/await in Objective-C?

Accepted Answer

No, RWPromiseKit uses traditional Promise patterns with `then` and `catch` methods. Objective-C lacks native async/await, so this library provides a chaining alternative similar to JavaScript Promises.

Question 3

RWPromiseKit vs GCD: which one should I use?

Accepted Answer

Use RWPromiseKit for cleaner error handling and chaining multiple async operations with utilities like `all` and `race`. GCD is better for low-level concurrency control, but RWPromiseKit abstracts GCD blocks into more maintainable Promise patterns.

Question 4

How to handle errors with RWPromiseKit?

Accepted Answer

Use the `catch` method to handle rejections; errors can be triggered by throwing exceptions in `then` blocks or calling `reject`, as shown in the basic example in the README.

Question 5

Is RWPromiseKit stable for production use?

Accepted Answer

The README notes incomplete unit tests and complicated test cases, so it may not be fully stable. Consider it for projects comfortable with potential issues or willing to contribute to testing and documentation.

Question 6

Can I use RWPromiseKit with Swift code?

Accepted Answer

Yes, but since it's an Objective-C library, you'll need to bridge it in Swift projects. However, for Swift, native alternatives like Combine or async/await are often more efficient and better integrated.
