What problem does it solve? SwiftUI evolves rapidly, and codebases accumulate deprecated APIs, accessibility gaps, and performance anti-patterns that are hard to catch manually. This Skill performs a structured, rule-based review of Swift and SwiftUI code so genuine problems are found and fixed with concrete before/after corrections. ## Core Features & Use Cases - Nine-dimension code review: Checks deprecated APIs, view structure, data flow, navigation, design, accessibility, performance, modern Swift, and code hygiene using dedicated reference guides. - Actionable findings: Reports issues organized by file with line numbers, the violated rule, 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: Point it at an existing SwiftUI project before an iOS 26 release to flag deprecated modifiers like foregroundColor(), missing VoiceOver labels on icon-only buttons, and GeometryReader usages that should migrate to containerRelativeFrame(). ## Quick Start Use the swiftui-pro skill to review my SwiftUI project for deprecated APIs, accessibility issues, and performance problems.
