Apply platform accessibility best practices to SwiftUI, UIKit, and AppKit code. Essential companion to any SwiftUI, UIKit, or AppKit skill — always use together. Use whenever writing, editing, or reviewing ANY SwiftUI views, UIKit view controllers, AppKit views/window controllers, or platform UI — even when the user doesn't mention accessibility. Also use when the user mentions VoiceOver, Voice Control, Dynamic Type, Reduce Motion, screen reader, a11y, WCAG, accessibility audit, Nutrition Labels, accessibilityLabel, UIAccessibility, NSAccessibility, assistive technologies, or Switch Control. Not for server-side Swift, non-UI packages, or CLI tools.
Expert SwiftUI development guidelines with MVVM architecture and modern Swift best practices
Use when reviewing or generating Swift code for modern idiom correctness — catches outdated APIs, pre-Swift 5.5 patterns, and Foundation legacy usage that Claude defaults to
Write, review, or improve Swift APIs using Swift API Design Guidelines for naming, argument labels, documentation comments, terminology, and general conventions. Use when designing new APIs, refactoring existing interfaces, or reviewing API clarity and fluency.
Thread-safe data persistence in Swift using actors — in-memory cache with file-backed storage. Use when building local storage layers, offline-first patterns, or any shared mutable state that needs both concurrency safety and disk persistence.
This skill should be used when the user asks to "add SF Symbols", "animate icons", "use symbol effects", "apply symbol rendering mode", "add bounce/pulse effect", or needs SwiftUI iconography API reference. Provides SF Symbols usage, rendering modes (monochrome, hierarchical, multicolor, palette), symbol effects, and variable values.
Non-glass SwiftUI APIs from WWDC 2025 (iOS 26, macOS 26, visionOS 26). Covers @Animatable macro, TextEditor with AttributedString/AttributedTextSelection/AttributedTextFormattingDefinition, FindContext, WebView/WebPage, UIHostingSceneDelegate, ToolbarSpacer, Slider ticks, windowResizeAnchor, dragContainer, draggable(containerItemID:), scrollEdgeEffectStyle, tabBarMinimizeBehavior. Use when building rich text editors, embedding web content, bridging UIKit scenes to SwiftUI, or configuring scroll edge effects and tab bar minimization. DO NOT use for Liquid Glass design patterns (use apple-liquid-glass-design), general Swift or pre-iOS 26 SwiftUI (use swiftui-ui-patterns).
Use when building UI with Apple's Liquid Glass material for iOS 26, iPadOS 26, macOS 26 - covers glassEffect, GlassEffectContainer, backgroundExtensionEffect, morph animations, toolbar grouping, button styles (.glass, .glassProminent), Icon Composer, ConcentricRectangle, scroll edge effects, and adoption best practices across SwiftUI, UIKit, and AppKit.
This skill should be used when the user asks to "write tests", "add unit tests", "implement UI tests", "analyze test coverage", "use XCTest", "use Swift Testing", "test SwiftUI views", or needs iOS/macOS testing guidance. Provides testing strategies, XCTest and Swift Testing framework patterns, and SwiftUI-specific testing techniques.
Comprehensive macOS app development with Swift 6.2, SwiftUI, SwiftData, Swift Concurrency, Foundation Models, Swift Testing, ScreenCaptureKit, and app distribution. Use when building native Mac apps, implementing windows/scenes/navigation/menus/toolbars, persisting data with SwiftData (@Model, @Query,
Expert iOS development skill covering SwiftUI, UIKit, Core Data, App Store guidelines, and performance optimization. Use this skill when building, reviewing, or debugging iOS apps - views, navigation, data persistence, animations, or submission preparation. Triggers on SwiftUI layout and state management, UIKit view controller lifecycle, Core Data model design and migrations, App Store Review Guidelines compliance, memory and rendering performance profiling, and Swift concurrency patterns for iOS.
