swiftui-animation
Implement, review, and improve SwiftUI animations with modern iOS 17+ APIs and accessibility support.
- Covers explicit animations with
withAnimation, implicit animations with.animation(_:body:)and.animation(_:value:), and spring presets (.smooth,.snappy,.bouncy) - Supports multi-phase animations via
PhaseAnimator, complex choreography withKeyframeAnimator, and shared-element transitions usingmatchedGeometryEffectandmatchedTransitionSource - Includes SF Symbol effects (bounce, pulse, variableColor, breathe, rotate, wiggle) with rendering modes and variable color fills for semantic icon animation
- Provides
@Animatablemacro for custom animatable types, asymmetric transitions, content transitions for in-place text/number changes, and accessibility reduce-motion handling - Common mistakes section covers scope precision, expensive work in animation closures, missing accessibility checks, and proper view placement for navigation zoom transitions
SwiftUI Animation (iOS 26+)
Review, write, and fix SwiftUI animations. Apply modern animation APIs with correct timing, transitions, and accessibility handling using Swift 6.3 patterns.

1.5Kios-localization
Implement, review, or improve localization and internationalization in iOS/macOS apps — String Catalogs (.xcstrings), generated localizable symbols, stable key naming, LocalizedStringKey, LocalizedStringResource, pluralization, FormatStyle for numbers/dates/measurements, right-to-left layout, Dynamic Type, and locale-aware formatting. Use when adding multi-language support, setting up String Catalogs, enabling generated symbols for compile-time-safe localization keys, handling plural forms, formatting dates/numbers/currencies for different locales, testing localizations, or making UI work correctly in RTL languages like Arabic and Hebrew.
