Swiftui Expert Skill

This is a comprehensive reference guide for writing production SwiftUI code with current best practices baked in. Use it when you need authoritative answers on state management (@State vs @Binding vs @Observable), view composition patterns, performance optimization for lists and animations, or iOS 26+ Liquid Glass adoption. The decision tree walks you through reviewing, improving, or implementing features with specific checks at each step. What I like here is the specificity: it tells you exactly when to use which property wrapper, how to avoid common animation pitfalls like the deprecated animation modifier without a value parameter, and performance traps like inline filtering in ForEach. The accessibility guidance is also concrete (prefer Button over onTapGesture, use @ScaledMetric for Dynamic Type). Treat this as your SwiftUI facts layer when you want to avoid cargo culting Stack Overflow patterns.
