Use when migrating from Realm to SwiftData - comprehensive migration guide covering pattern equivalents, threading model conversion, schema migration strategies, CloudKit sync transition, and real-world scenarios
Expert-level Swift development for iOS, macOS with SwiftUI, Combine, and modern Swift 5.9+
SwiftUI NavigationStack, NavigationSplitView, and navigation transition patterns for iOS 16-18+. Covers @Observable coordinators, zoom transitions, hero animations, sheet vs push decisions, multi-step flows, anti-patterns, performance, accessibility, deep linking, and state restoration. This skill should be used when designing navigation hierarchies, implementing screen transitions, choosing between sheet and push, orchestrating multi-step flows, using @Observable with @Environment and @Bindable, or reviewing navigation code for anti-patterns.
Pattern extraction and skill generation for mobile development sessions. Automatically learns from your coding patterns.
This blog post explores how to optimize HTTP client selection in Flutter applications based on the platform, using Cronet on Android and Cupertino's native client on iOS for improved performance and caching.
Implement, review, or improve SwiftUI animations and transitions. Use when adding implicit or explicit animations with withAnimation, configuring spring animations (.smooth, .snappy, .bouncy), building phase or keyframe animations with PhaseAnimator/KeyframeAnimator, creating hero transitions with matchedGeometryEffect or matchedTransitionSource, adding SF Symbol effects (bounce, pulse, variableColor, breathe, rotate, wiggle), implementing custom Transition or CustomAnimation types, or ensuring animations respect accessibilityReduceMotion.
Build SwiftUI layouts using stacks, grids, lists, scroll views, forms, and controls. Covers VStack/HStack/ZStack, LazyVGrid/LazyHGrid, List with sections and swipe actions, ScrollView with ScrollViewReader, Form with validation, Toggle/Picker/Slider, .searchable, and overlay patterns. Use when building data-driven layouts, collection views, settings screens, search interfaces, or transient overlay UI.

Integrates Firebase Crashlytics into Flutter apps. Use when setting up crash reporting, handling fatal and non-fatal errors, customizing crash reports with keys/logs/user identifiers, or configuring opt-in reporting.
Jetpack Compose expert skill for Android UI development. Guides state management decisions (@Composable, remember, mutableStateOf, derivedStateOf, State hoisting), view composition and structure, Modifier chains, lazy lists, navigation, animation, side effects, theming, accessibility, and performance optimization. Backed by actual androidx source code analysis. Use this skill whenever the user mentions Compose, @Composable, remember, LaunchedEffect, Scaffold, NavHost, MaterialTheme, LazyColumn, Modifier, recomposition, Style, styleable, MutableStyleState, or any Jetpack Compose API. Also trigger when the user says "Android UI", "Kotlin UI", "compose layout", "compose navigation", "compose animation", "material3", "compose styles", "styles api", or asks about modern Android development patterns. Even casual mentions like "my compose screen is slow" or "how do I pass data between screens" should trigger this skill.
Build, refactor, or review macOS menubar apps that use Tuist and SwiftUI. Use when creating or maintaining LSUIElement menubar utilities, defining Tuist targets/manifests, implementing model-client-store-view architecture, adding script-based launch flows, or validating reliable local build/run behavior without Xcode-first workflows.
Orchestrate Xcode build optimization by benchmarking first, running the specialist analysis skills, prioritizing findings, requesting explicit approval, delegating approved fixes to xcode-build-fixer, and re-benchmarking after changes. Use when a developer wants an end-to-end build optimization workflow, asks to speed up Xcode builds, wants a full build audit, or needs a recommend-first optimization pass covering compilation, project settings, and packages.
