Can this skill detect retain cycles in Swift?

Yes, it specifically checks for the use of [weak self] in stored closures and ensures delegate properties are marked as weak to prevent memory leaks.

Does it enforce error handling best practices?

Yes, it verifies that errors are handled explicitly, discourages empty catch blocks, and promotes the use of LocalizedError for better debugging.

Does it support modern SwiftUI state management?

Absolutely. It includes specific checks for @Observable, @Bindable, and @ObservationIgnored to ensure proper data flow and performance.

How does it help with Swift Concurrency?

The skill audits actor isolation, Sendable conformance, and potential reentrancy bugs, ensuring your async/await code is thread-safe and efficient.
