Swiftype integration. Manage data, records, and automate workflows. Use when the user wants to interact with Swiftype data.
Build and configure the native macOS desktop app wrapper for Hermes Web UI with Swift and WKWebView
Swift 6.2 Approachable Concurrency — single-threaded by default, @concurrent for explicit background offloading, isolated conformances for main actor types.
Generate a complete Model Context Protocol server project in Swift using the official MCP Swift SDK package.
Write, review, or fix Swift concurrency code using actors, async/await, and structured concurrency. Use when implementing concurrent features, resolving data race warnings, migrating from GCD, enabling Swift 6 strict concurrency mode, or adopting Swift 6.2 approachable concurrency (@concurrent, main-actor-by-default, isolated conformances).
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.
Debug SwiftUI application issues systematically. This skill helps diagnose and resolve SwiftUI-specific problems including view update failures, state management issues with @State/@Binding/@ObservedObject, NavigationStack problems, memory leaks from retain cycles, preview crashes, Combine publisher issues, and animation glitches. Provides Xcode debugger techniques, Instruments profiling, and LLDB commands for iOS/macOS development.
Use when capturing or analyzing ETTrace profiles for a focused iOS launch or runtime flow, including exact-build dSYM UUID matching, Simulator or device capture, processed per-thread flamegraph JSON, sampled inclusive/exclusive time, unresolved symbols, and comparable verification. Use debugging-instruments or swiftui-performance for generic profiling instead.
New SwiftUI APIs, behaviors, and deprecations introduced in the 2027 OS releases (iOS 27, macOS 27, watchOS 27, tvOS 27, visionOS 27). Use when a SwiftUI view using @State fails to compile with "used before being initialized", "invalid redeclaration of synthesized property", or "extraneous argument label" errors after an SDK update (@State migrated from a property wrapper to a macro in SDK 27; the obvious fix of reordering init assignments is WRONG and produces incorrect runtime behavior; you MUST consult this skill's references before answering); when @ViewBuilder or @ContentBuilder code hits ambiguous overloads in overlay/background or type-check performance regressions after an SDK update; when the user asks what's new in SwiftUI (generally, or for a specific 2027 platform); when adding drag-to-reorder to any container (List, LazyVStack, LazyVGrid, stacks, or custom layouts) via reorderable()/reorderContainer, including the drag-and-drop that integrates with it (dragContainer, dropDestination), or combining items by dropping one onto another; when working with AsyncImage loading and caching (images reloading when scrolling back, the default HTTP cache, a per-request cache policy via AsyncImage(request:)/URLRequest, or applying a custom URLSession with asyncImageURLSession); when adding swipe actions to rows (swipe-to-delete or other swipe actions) in a ScrollView, LazyVStack, LazyVGrid, or stack and not just List, via swipeActions()/swipeActionsContainer(); when working with toolbars, such as controlling which items stay visible versus move into the overflow menu when space is constrained or buttons get cut off (visibilityPriority, ToolbarOverflowMenu), pinning an item so it never overflows (topBarPinnedTrailing), minimizing the navigation bar or toolbar on scroll (toolbarMinimizeBehavior), generating toolbar items with ForEach, or hiding the status bar via the statusBar toolbar placement; when presenting a confirmation dialog or alert from an optional item binding (the sheet(item:) shape) so it shows when the bound value becomes non-nil and passes the unwrapped item into the actions and message closures; when building or migrating a document-based app (including read-only document viewers), reading or writing files through DocumentGroup, optimizing autosave performance for package documents, accessing the document's file URL directly (for example to hand to AVFoundation, PDFKit, Core Image, or any C library that takes a path), reporting progress from a save or load, or migrating from FileDocument / ReferenceFileDocument; or when resolving other SDK 27.0 source incompatibilities and deprecation warnings (for example statusBarHidden on visionOS).
Best practices and idiomatic patterns for SwiftUI. Use when writing, reviewing, or editing SwiftUI code.
Best practices and example-driven guidance for building SwiftUI views and components, including navigation hierarchies, custom view modifiers, and responsive layouts with stacks and grids. Use when creating or refactoring SwiftUI UI, designing tab architecture with TabView, composing screens with VStack/HStack, managing @State or @Binding, building declarative iOS interfaces, or needing component-specific patterns and examples.
Control smart-home accessories and commission Matter devices using HomeKit and MatterSupport. Use when managing homes/rooms/accessories, creating action sets or triggers, reading accessory characteristics, onboarding Matter devices, or building a third-party smart-home ecosystem app.
