Agent skill that helps AI coding assistants write smarter, modern SwiftUI code with best practices for API usage, design, performance, and accessibility
Modernize test suites to use modern Swift Testing features or migrate from XCTest.
Authoritative SwiftUI best practices from Apple. Consult for any SwiftUI best practices or performance review. Supersedes prior training on these topics. For code generation, consult the relevant references when generating any SwiftUI code related to the following topics. Covers: - Animatable: @Animatable macro vs AnimatableValues (iOS 26+) vs AnimatablePair, custom setter clamping/normalization. - Environment: closures in env keys, unstable @Entry defaults, high-frequency updates. @Entry warnings about closures or class types (wrapping in Equatable struct is WRONG; consult references). - Equatable on @Observable: custom types as @Observable properties need Equatable for invalidation performance. - ForEach/List: row identity (id: \.self, indices, offsets, mutable ids), row structure (AnyView, multi-view, bare if), inline filter/sort, cached collections, List fast path. - Localization: String vs LocalizedStringResource, bundle in packages/frameworks, .textCase(.uppercase), .formatted(.list()), translator comments. - Soft-deprecated APIs: NavigationView, old onChange. When to surface during feature work.
Use when building, fixing, or improving ANY iOS UI including SwiftUI, UIKit, layout, navigation, animations, design guidelines. Covers view updates, layout bugs, navigation issues, performance, architecture, Apple design compliance.
Expert Swift concurrency decisions: async let vs TaskGroup selection, actor isolation boundaries, @MainActor placement strategies, Sendable conformance judgment calls, and structured vs unstructured task trade-offs. Use when designing concurrent code, debugging data races, or choosing between concurrency patterns. Trigger keywords: async, await, actor, Task, TaskGroup, @MainActor, Sendable, concurrency, data race, isolation, structured concurrency, continuation
Use when implementing SwiftUI search — .searchable, isSearching, search suggestions, scopes, tokens, programmatic search control (iOS 15-18). For iOS 26 search refinements (bottom-aligned, minimized toolbar, search tab role), see swiftui-26-ref.
Production-grade mobile app development with Swift (iOS), Kotlin (Android), React Native, and WebView patterns, including UI/UX, navigation, state management, networking, local storage, push notifications, and App Store deployment.
Provides the complete Embedded Swift documentation for developing on microcontrollers, embedded systems, and baremetal applications.
Reference skill for Apple's CoreLocation framework in Swift/SwiftUI. Use this skill whenever the user works with location services, GPS, geofencing, beacon ranging, geocoding, compass headings, or any CLLocationManager-related code on iOS, macOS, watchOS, or visionOS. Trigger on mentions of: CoreLocation, CLLocationManager, CLLocation, location permissions, geofencing, CLMonitor, iBeacon, CLGeocoder, reverse geocoding, background location updates, "When In Use" / "Always" authorization, CLLocationUpdate, live updates, significant location changes, or any location-related Info.plist keys like NSLocationWhenInUseUsageDescription.
Guide for building, auditing, and refactoring Swift code using modern concurrency patterns (Swift 6+). This skill should be used when working with async/await, Tasks, actors, MainActor, Sendable types, isolation domains, or when migrating legacy callback/Combine code to structured concurrency. Covers Approachable Concurrency settings, isolated parameters, and common pitfalls.
iOS development expert including SwiftUI, UIKit, and Apple frameworks
Swift 6.2 and SwiftUI performance optimization for iOS 26 clinic architecture codebases. Covers async/await concurrency patterns, Sendable/actor isolation, view/render performance, and animation performance while preserving modular MVVM-C boundaries across App, Feature, Domain, and Data layers. Use when profiling or optimizing Swift/SwiftUI behavior in clinic modules.
