What problem does it solve? SwiftUI evolves rapidly, and codebases accumulate deprecated APIs, inefficient patterns, and accessibility gaps that are hard to catch manually. This Skill performs a structured, rule-based review of Swift and SwiftUI code so issues are found before they reach production. ## Core Features & Use Cases - Nine-dimension code review: Checks deprecated APIs, view structure, data flow, navigation, design, accessibility, performance, Swift concurrency, and code hygiene using dedicated reference guides. - Actionable findings: Reports each issue with file, line, the rule violated, and a before/after code fix, ending with a prioritized summary. - Partial reviews: Load only the relevant reference files when reviewing a specific concern, such as accessibility or performance. - Use Case: Before shipping an iOS 26 app update, run a full review to replace deprecated modifiers like foregroundColor(), fix icon-only buttons that break VoiceOver, and move expensive logic out of view bodies. ## Quick Start Review the SwiftUI code in this project and report any deprecated APIs, accessibility issues, and performance problems with suggested fixes.
