Quick Reference

Issue Type	Reference
View extraction, modifiers, body complexity	references/view-composition.md
@State, @Binding, @Observable, @Bindable	references/state-management.md
LazyStacks, AnyView, ForEach, identity	references/performance.md
VoiceOver, Dynamic Type, labels, traits	references/accessibility.md

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?
