Build native and cross-platform mobile applications for iOS and Android with optimized performance and platform integration. Use when you need SwiftUI or Jetpack Compose development, React Native or Flutter cross-platform apps, offline-first architecture, biometric authentication, push notifications, deep linking, app startup optimization, or mobile-specific UX patterns and gesture handling.
Use when building ANY 2D or 3D game, game prototype, or interactive simulation with SpriteKit, SceneKit, or RealityKit. Covers scene graphs, ECS architecture, physics, actions, game loops, rendering, SwiftUI integration, SceneKit migration.
Guide for building Apple-platform applications with Apollo iOS, the strongly-typed GraphQL client for Swift. Use this skill when: (1) adding Apollo iOS to a Swift Package Manager or Xcode project, (2) configuring `apollo-codegen-config.json` and running code generation, (3) configuring an `ApolloClient` with auth, interceptors, and caching, (4) writing queries, mutations, or subscriptions from SwiftUI views, (5) writing tests against generated operation mocks.
Automatically discover mobile development skills when working with iOS, Android, Swift, SwiftUI, React Native, mobile development, SwiftData, or app development. Activates for mobile development tasks.
Apple Human Interface Guidelines (HIG) reference for designing iOS, iPadOS, macOS, tvOS, visionOS, watchOS apps. Covers UI components, layout, accessibility, typography, navigation, inputs, and platform technologies. Use when designing Apple platform UIs, reviewing SwiftUI/UIKit patterns, or applying HIG design principles to any app.
Reverse-engineers a UI animation from a screen recording — extracts frames, tracks motion per frame, fits easing and spring curves, annotates choreography, and emits CSS, Motion/Framer Motion, SwiftUI, React Native, or UIKit code. Use when the user shares or uploads a screen recording or video of a UI animation, or asks to "reverse engineer this animation", "recreate this animation", "match this easing", "extract the animation curve", "figure out the spring from this video", "copy this transition from a video", "how does this animation work", or "reproduce this motion".
UI/UX design intelligence for web and mobile.

Design system skills for modern Apple platform UI including Liquid Glass, animations, and visual design patterns. Use when implementing new design language features.
Implement, review, or improve maps and location features in iOS/macOS apps using MapKit and CoreLocation. Use when working with Map views, annotations, markers, polylines, user location tracking, geocoding, reverse geocoding, search/autocomplete, directions and routes, geofencing, region monitoring, CLLocationUpdate async streams, or location authorization flows. Trigger for any task involving maps, coordinates, addresses, places, directions, distance calculations, or location-based features in Swift apps.
Implement, review, or improve photo picking, camera capture, and media handling in iOS apps. Use when working with PhotosPicker, PHPickerViewController, camera capture sessions (AVCaptureSession), photo library access, image loading and display, video recording, or media permissions. Trigger for any task involving selecting photos from the library, taking pictures, recording video, processing images, or handling photo/camera privacy permissions in Swift apps.
Implement, review, or improve widgets, Live Activities, and controls using WidgetKit and ActivityKit. Use when building home screen, Lock Screen, or StandBy widgets with timeline providers; when creating interactive widgets with Button/Toggle and AppIntent actions; when adding Live Activities with Dynamic Island layouts (compact, minimal, expanded); when building Control Center widgets with ControlWidgetButton/ControlWidgetToggle; when configuring widget families, refresh budgets, deep links, push-based reloads, or Liquid Glass rendering; or when setting up widget extensions, App Groups, and entitlements.
Add Apple Pencil drawing, canvas views, tool pickers, and ink serialization using PencilKit. Use when building drawing apps, annotation features, handwriting capture, signature fields, or any Apple Pencil-powered experience on iOS/iPadOS/visionOS.
