Patterns for sharing code between macOS and iOS in SwiftUI apps. Covers project structure (70% shared / 15% macOS / 15% iOS), platform abstraction via protocols and #if os() conditional compilation, adaptive navigation (NavigationSplitView on Mac/iPad → NavigationStack on iPhone), shared components with platform styling, iOS-specific extensions (custom keyboard extension, interactive widgets, share extension, action extension, Control Center widget, lock screen widget), App Groups for data sharing with extensions, CloudKit sync monitoring, JSON export/import, schema versioning and migration, URL scheme deep linking, and the full macOS→iOS migration checklist. Use when building apps that target both macOS and iOS, when adding iOS support to a macOS app, when building widgets or keyboard extensions, or when setting up iCloud sync with SwiftData.
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.
The Composable Architecture (TCA) - A library for building Swift applications with state management, composition, and testability
Use when implementing any Swift or SwiftUI feature or bugfix, before writing implementation code
Use this skill when brainstorming, designing, or planning any Swift feature. This is the right skill whenever the user describes a feature they want to build, asks "how should I implement X", wants to think through a design, or starts with something like "I want to add..." or "let's plan...". Use it even if they don't explicitly say "brainstorm" — if there's a feature to figure out, start here before touching any code.
Swift language patterns and best practices including concurrency, performance, and modern idioms. Use for Swift language-level code review or architecture guidance.
Implement, review, or improve accessibility in iOS/macOS apps with SwiftUI and UIKit. Use when adding VoiceOver support with accessibility labels, hints, values, and traits; when grouping or reordering accessibility elements; when managing focus with @AccessibilityFocusState; when supporting Dynamic Type with @ScaledMetric; when building custom rotors or accessibility actions; when auditing a11y compliance; or when adapting UI for assistive technologies and system accessibility preferences.
Implement, review, or debug push notifications in iOS/macOS apps — local notifications, remote (APNs) notifications, rich notifications, notification actions, silent pushes, and notification service/content extensions. Use when working with UNUserNotificationCenter, registering for remote notifications, handling notification payloads, setting up notification categories and actions, creating rich notification content, or debugging notification delivery. Trigger for any task involving alerts, badges, sounds, background pushes, or user notification permissions in Swift apps.
Apply platform accessibility best practices to SwiftUI, UIKit, and AppKit code. Essential companion to any SwiftUI, UIKit, or AppKit skill — always use together. Use whenever writing, editing, or reviewing ANY SwiftUI views, UIKit view controllers, AppKit views/window controllers, or platform UI — even when the user doesn't mention accessibility. Also use when the user mentions VoiceOver, Voice Control, Dynamic Type, Reduce Motion, screen reader, a11y, WCAG, accessibility audit, Nutrition Labels, accessibilityLabel, UIAccessibility, NSAccessibility, assistive technologies, or Switch Control. Not for server-side Swift, non-UI packages, or CLI tools.
This skill should be used when the user asks to "add SF Symbols", "animate icons", "use symbol effects", "apply symbol rendering mode", "add bounce/pulse effect", or needs SwiftUI iconography API reference. Provides SF Symbols usage, rendering modes (monochrome, hierarchical, multicolor, palette), symbol effects, and variable values.
Expert guidance on building, debugging, and testing multiplatform iOS/Android apps and frameworks with Skip (skip.dev). Use when developers mention: (1) Skip, Skip.dev, skip-tools, or SkipStack, (2) building a multiplatform iOS+Android app from Swift/SwiftUI, (3) Skip Fuse (native) or Skip Lite (transpiled) modes, (4) transpiling Swift to Kotlin, (5) SwiftUI to Jetpack Compose bridging, (6) skip.yml configuration, (7) debugging Android builds from Xcode, (8) Skip CLI commands (skip create/init/test/export), (9) conditional compilation with #if SKIP or #if os(Android), (10) Skip Comments (SKIP INSERT/REPLACE/DECLARE/NOWARN), (11) bridging Swift and Kotlin code, (12) Skip module dependencies or Android Gradle configuration.
Create media playback experiences using AVKit. Use when adding video players with AVPlayerViewController, enabling Picture-in-Picture, routing media with AirPlay, using SwiftUI VideoPlayer views, configuring transport controls, displaying subtitles and closed captions, or integrating AVFoundation playback with system UI.
