This skill reviews Swift concurrency code for correctness, modern API usage, and common async/await pitfalls. It follows a structured review process: checking actor isolation, structured concurrency, cancellation, and bridging patterns against a bank of reference guides. It helps Swift developers, iOS architects, and DevEx teams enforce Swift 6.2 concurrency best practices without relying solely on human review.
Follow the documented setup, then try a first task.
