SwiftUI best practices, pitfalls, and modern APIs. Invoke when user asks SwiftUI UI, state, navigation, lists, sheets, performance, or accessibility help.
Generate a complete Model Context Protocol server project in Swift using the official MCP Swift SDK package.
SwiftUI framework concepts including property wrappers, state management, and reactive UI patterns.
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.
Guides SwiftUI navigation using the Navigator/NavigatorUI library—NavigationDestination enums, ManagedNavigationStack, NavigationLink(to:label), deep linking (send/onNavigationReceive), checkpoints, dismissible views, and modular/provided destinations. Use when implementing or discussing SwiftUI navigation with Navigator, deep linking, checkpoints, or NavigatorUI.
SwiftUI animation patterns — implicit/explicit animations, transitions, phase/keyframe animations, the Animatable protocol, and the @Animatable macro. Use when implementing animations, transitions, or motion in SwiftUI views.
Use when implementing gesture composition (simultaneous, sequenced, exclusive), adaptive layouts (ViewThatFits, AnyLayout, size classes), or choosing architecture patterns (MVVM vs TCA vs vanilla, State-as-Bridge). Covers advanced SwiftUI patterns beyond basic views.
System-wide keyboard shortcut registration on macOS using NSEvent monitoring (simple, app-level) and Carbon EventHotKey API (reliable, system-wide). Covers NSEvent.addGlobalMonitorForEvents and addLocalMonitorForEvents, CGEvent tap for keystroke simulation, Carbon RegisterEventHotKey for system-wide hotkeys, modifier flag handling (.deviceIndependentFlagsMask), common key code mappings, debouncing, Accessibility permission requirements (AXIsProcessTrusted), and SwiftUI .onKeyPress for in-app shortcuts. Use when implementing global keyboard shortcuts, hotkey-triggered panels, or system-wide key event monitoring.
Swift language patterns and best practices including concurrency, performance, and modern idioms. Use for Swift language-level code review or architecture guidance.
Expert guidance for designing, implementing, migrating, and debugging SwiftData persistence in Swift and SwiftUI apps. Use when working with @Model schemas, @Relationship/@Attribute rules, Query or FetchDescriptor data access, ModelContainer/ModelContext configuration, CloudKit sync, SchemaMigrationPlan/history APIs, ModelActor concurrency isolation, or Core Data to SwiftData adoption/coexistence.
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.
Swift Testing patterns — structs over classes, async confirmations, parameterized tests, exit tests, attachments, common agent mistakes. Use when writing, reviewing, or migrating Swift Testing code.
