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.

Reviews Swift code for concurrency safety, memory management, and modern SwiftUI patterns to ensure high-quality iOS and macOS development.

About

This skill equips Claude with specialized knowledge to audit Swift source files for critical issues such as thread safety, memory leaks, and improper error handling. It excels at identifying subtle bugs in modern Swift features like actor isolation, Sendable conformance, and the @Observable macro. By using this skill, developers can automate the detection of retain cycles, force unwraps, and reentrancy bugs, ensuring their code follows the latest Apple development standards and best practices for performance and stability.
