How does this skill handle legacy iOS APIs?

It utilizes CheckedContinuations to wrap completion handlers and delegate methods into modern async functions, allowing legacy code to work seamlessly with async/await.

Does it support Combine integration?

Absolutely, it includes patterns for converting publishers to async sequences and bridging the two frameworks for hybrid reactive architectures.

Can it help with UI threading issues?

Yes, it specializes in using @MainActor and MainActor.run to ensure all UI updates happen safely on the main thread, preventing common threading crashes.

How does it handle cooperative cancellation?

The skill implements checks using Task.checkCancellation() and Task.isCancelled to ensure background tasks stop gracefully when no longer needed.
