Question 1

How to migrate from BrightFutures to Swift async/await?

Accepted Answer

Use the async `get()` method on futures within an async context, as shown in the README: `let user = try await userFuture.get()`. Gradually refactor future chains into native async functions for better performance and readability.

Question 2

BrightFutures vs Combine: which should I use for async Swift?

Accepted Answer

BrightFutures is a standalone futures library focused on functional composition, while Combine is Apple's reactive framework for event handling. With Swift's async/await, both are becoming legacy, but Combine offers tighter integration with Apple's ecosystem if you need reactive programming.

Question 3

Is BrightFutures still maintained or safe to use?

Accepted Answer

No, the README states it has reached end-of-life and is obsolete due to Swift's async/await. It's not recommended for new projects, and existing users should plan migration.

Question 4

How to handle errors in BrightFutures without callbacks?

Accepted Answer

Leverage the `recover` method to provide default values or `recoverWith` for alternative futures when errors occur, ensuring type-safe handling without nested completion blocks.

Question 5

What are good alternatives to BrightFutures now?

Accepted Answer

Swift's native async/await is the primary alternative, offering built-in concurrency. For reactive patterns, Combine or third-party libraries like RxSwift might be considered, but async/await is the standard forward path.

Question 6

How to cancel a running task in BrightFutures?

Accepted Answer

BrightFutures uses invalidation tokens to ignore callbacks, but it doesn't cancel underlying tasks. For task cancellation, you'd need to implement external mechanisms like NSProgress or wrap operations in cancellable closures.
