What problem does it solve? SwiftUI evolves quickly, and codebases accumulate deprecated APIs, outdated data flow patterns, and accessibility gaps that are hard to catch manually. This Skill applies a structured rule set while writing SwiftUI code and runs a systematic review pass across nine focus areas, reporting only genuine defects with concrete before/after fixes. ## Core Features & Use Cases - Modern API enforcement: Flags deprecated calls like foregroundColor(), NavigationView, and cornerRadius() and shows the current replacements. - Nine review focus areas: Covers modern APIs, views and animation, data flow, navigation, HIG design, accessibility, performance, Swift concurrency, and code hygiene, each backed by a dedicated reference file. - Structured review output: Organizes findings by file with line numbers, rule names, before/after code fixes, and a prioritized summary. - Use Case: While building an iOS settings screen, ask for a review and receive findings such as an icon-only button missing a VoiceOver label, a Binding(get:set:) in the view body, and a deprecated foregroundColor() call, each with a ready-to-apply fix. ## Quick Start Review my SwiftUI code for deprecated APIs, data flow issues, and accessibility problems, and show before-and-after fixes for each finding.
