Gates (review workflow)#

Complete in order; do not skip ahead.

1. Anchor scope — Pass when: every reviewed file is listed as a repo-relative .swift path (or the review explicitly states “none opened / N/A” with reason).
2. Reference before critique — Pass when: for any non-trivial body, modifier chain, or wrapper-ownership question, you have opened the matching references/*.md row from the table above or you state “not needed” with one line why.
3. Evidence-bound findings — Pass when: each substantive issue includes [FILE:LINE] (or a bounded line range) before recommendations; symbols/snippets may supplement but not replace the location anchor; no finding that rests only on “typical SwiftUI” without pointing at this code.

Review Checklist#

• View body under 10 composed elements (extract subviews)
• Modifiers in correct order (padding before background)
• @StateObject for view-owned objects, @ObservedObject for passed objects
• @Bindable used for two-way bindings to @Observable (iOS 17+)
• LazyVStack/LazyHStack for scrolling lists with 50+ items
• No AnyView (use @ViewBuilder or generics instead)
• ForEach uses stable Identifiable IDs (not array indices)
• All images/icons have accessibilityLabel
• Custom controls have accessibilityAddTraits(.isButton)
• Dynamic Type supported (no fixed font sizes)
• .task modifier for async work (not onAppear + Task)

When to Load References#

• Complex view bodies or modifier chains -> view-composition.md
• Property wrapper usage (@State, @Observable) -> state-management.md
• List performance or view identity issues -> performance.md
• VoiceOver or accessibility implementation -> accessibility.md

Review Questions#

1. Could this large view body be split into smaller, reusable Views?
2. Is modifier order intentional? (padding -> background -> frame)
3. Is @StateObject/@ObservedObject usage correct for ownership?
4. Could LazyVStack improve this ScrollView's performance?
5. Would VoiceOver users understand this interface?
