Question 1

How to implement exponential backoff with Retry in Swift?

Accepted Answer

Use the custom retry strategy to define a delay that increases exponentially. For example, adapt the README's custom strategy that multiplies delay by 2 each retry, or set a base delay and exponent for classic backoff patterns.

Question 2

Retry library vs RxSwift retry operator: which is better?

Accepted Answer

If you're already using RxSwift, its built-in retry operator might be more integrated and reactive. Retry is better for non-reactive Swift code or when you need more control over retry strategies without RxSwift dependency, as it's inspired by but separate from RxSwiftExt.

Question 3

Can I use Retry for network requests in iOS apps?

Accepted Answer

Yes, Retry is ideal for retrying failed network calls. Use retryAsync to avoid blocking the main thread, and configure delays like exponential backoff to handle transient errors, though you'll need to handle HTTP-specific logic manually.

Question 4

How to avoid blocking the main thread with Retry?

Accepted Answer

Always use retryAsync for operations on the main thread. The README explicitly warns that sync retry can block the UI if delays are involved, so async version is recommended to maintain app responsiveness.

Question 5

Does Retry work with Apple's Combine framework?

Accepted Answer

Retry is a standalone library and doesn't integrate directly with Combine. For Combine-based projects, you might use Combine's retry operator or wrap Retry in custom publishers, but it's not optimized out-of-the-box.

Question 6

How to install Retry using Swift Package Manager?

Accepted Answer

Add the GitHub repository URL 'https://github.com/icanzilb/Retry.git' to your package manifest dependencies. The README confirms availability through SPM alongside CocoaPods for modern Swift projects.
