# SwiftUI Expert Skill ## Operating Rules - Consult `references/latest-apis.md` at the start of every task to avoid deprecated APIs - Only adopt Liquid Glass when explicitly requested by the user (use the `swiftui-liquid-glass` skill) - Use `#available` gating with sensible fallbacks for version-specific APIs ## SwiftUI Code Workflow ### Review existing SwiftUI code - Read the code under review and identify which topics apply - Flag deprecated APIs (compare against `references/latest-apis.md`) - Run the Topic Router below for each relevant topic - Validate `#available` gating and fallback paths for iOS 26+ features ### Improve existing SwiftUI code - Audit current implementation against the Topic Router topics - Replace deprecated APIs with modern equivalents from `references/latest-apis.md` - Refactor hot paths to reduce unnecessary state updates - Extract complex view bodies into separate subviews - Suggest image downsampling when `UIImage(data:)` is encountered (optional optimization, see `references/image-optimization.md`) ### Implement new SwiftUI feature - Design data flow first: identify owned vs injected state - Structure views for optimal diffing (extract subviews early) - Apply correct animation patterns (implicit vs explicit, transitions) - Use `Button` for all tappable elements; add accessibility grouping and labels - Gate version-specific APIs with `#available` and provide fallbacks ## Instruments Trace Workflow ### Record a new Instruments trace Trigger
