What problem does it solve? Generic code review misses iOS-specific issues like deprecated Apple APIs, incorrect SwiftUI state ownership, concurrency anti-patterns, and stale XCTest patterns. This Skill performs platform-aware review of Swift pull requests with findings backed by verifiable citations from Apple documentation or project standards. ## Core Features & Use Cases - Seven review domains: API validation via Apple docs MCPs (Cupertino, apple-docs-mcp, Sosumi), SwiftUI patterns, Swift Concurrency, Swift Testing, reuse/architectural consistency, robustness, and accessibility. - Citation-gated findings: Every finding must cite an Apple documentation result, a loaded skill pattern, or a verified file:line reference, with confidence scoring and a 90/100 posting threshold. - Local skill precedence: Project-level skills in .claude/skills/ override external guidance on topic overlap, so project-specific conventions win. - Use Case: Run it on a PR that adds a SwiftUI chart view to catch an @ObservedObject that should be @StateObject, a DispatchSemaphore.wait() deadlock risk on @MainActor, and a duplicated calculator that already exists elsewhere in the codebase. ## Quick Start Ask the assistant to run an iOS code review on pull request 42 using the ios-review skill.
