1Swift Concurrency ProThe swift-concurrency-pro skill reviews Swift code for concurrency correctness, modern API usage, and common async/await pitfalls. Agents scan known-dangerous patterns from reference hotspots, validate Swift 6.2 behavior, actor reentrancy and isolation, structured versus unstructured tasks, cancellation handling, async streams, bridging between sync and async code, legacy GCD interop, bug patterns, strict-concurrency diagnostics, and async test patterns. Core rules target Swift 6.2 with strict checking, prefer structured concurrency and async/await over closure APIs, and reject @unchecked Sendable as a quick fix. Findings are organized by file with line references, violated rules, and before/after fixes, ending in a prioritized summary of high-impact changes. Partial reviews can load only relevant reference files. The skill reports genuine problems without nitpicking and accepts GCD in low-level or performance-critical interop. Use when reading, writing, or reviewing Swift concurrency code, migrating legacy patterns, or resolving strict-concurrency compiler errors.7.9kinstalls
