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.
Use when building ANY macOS app — windows, menus, sandboxing, distribution, AppKit bridging, or macOS-specific SwiftUI patterns.
Design and build OpenAI-Codex-quality native macOS apps with the polish of Linear, Things 3, Granola, Notion Calendar, Arc Browser, Raycast, and Apple's own apps. Use this skill whenever the user is building, reviewing, or polishing a native Swift/SwiftUI Mac app — including AI coding tools, productivity apps, note-taking apps, design tools, dev tools, menu-bar utilities, or document-based apps. Targets macOS 14 (Sonoma) minimum and especially macOS 26 (Tahoe / Liquid Glass). Triggers on: macOS, Mac app, native Mac, SwiftUI Mac, AppKit, NSWindow, NSToolbar, NSStatusItem, NavigationSplitView, sidebar, toolbar, menu bar, MenuBarExtra, traffic lights, multi-window, document-based app, NSDocument, .commands, .keyboardShortcut, .onHover, .contextMenu, three-column layout, Inspector pattern, Liquid Glass macOS, Tahoe, command palette, Cmd-K, Dock badge, Sparkle, notarization, Developer ID, code editor, syntax highlighting, SF Mono, Stage Manager, Continuity, Spotlight, Quick Look, Apple Intelligence.
Drive a native Mac app (AppKit, SwiftUI, react-native-macos) through argent. Use when a list-devices entry has platform "macos", or the user names a Mac app, a macOS app or a native desktop app. Never for an iOS simulator, an iPhone, or an Electron or Chromium app (platform "chromium").
Xcode 26 and Apple platform update notes with a focus on Liquid Glass, Foundation Models Framework, and Apple Intelligence. Use when asked to explain, summarize, compare, or implement Xcode 26 era framework changes across SwiftUI, UIKit, AppKit, Foundation, App Intents, StoreKit, MapKit, WidgetKit, visionOS, or Swift language features.
Use when implementing SwiftUI animations, understanding VectorArithmetic, using @Animatable macro, zoom transitions, UIKit/AppKit animation bridging, choosing between spring and timing curve animations, or debugging animation behavior - comprehensive animation reference from iOS 13 through iOS 26
Build, scaffold, refactor, debug, review, and visually validate production Rust desktop interfaces with GPUI. Use for setting up a production-ready GPUI starter app; new GPUI apps or components; Entity, Context, action, async, and lifecycle architecture; Apple-style macOS UI, Liquid Glass or translucent materials, motion, gestures, focus, keyboard, accessibility, text input, IME, clipboard, drag and drop, menus, multi-window behavior, and restoration; packaging, CI, performance, and testing work; or translating selected Paper.design frames into maintainable GPUI code with screenshot comparison. Covers published GPUI and pinned Zed revisions, macOS/Linux/Windows boundaries, narrow AppKit interop, and stability audits.
Build, refactor, review, and debug native Apple-platform software in Swift. Use when working on `.swift` files, SwiftUI views, Observation-based state, `@Bindable` and binding flow, SwiftData-backed UI, scenes and windows, search/navigation structures, UIKit/AppKit interop, Liquid Glass adoption, macOS-native UX, or SwiftUI performance/accessibility. Trigger on requests to create or polish iOS, iPadOS, macOS, or visionOS features; clean up SwiftUI view structure; diagnose jank or invalidation storms; review app quality; or make a feature feel like a good Apple-platform citizen.
Python backend for Databricks Apps — FastAPI (default), Flask, Dash, Streamlit, Gradio, Reflex. **Default for a new Databricks App is `databricks-apps` (AppKit — Node/TypeScript/React) — reach for it first.** Use this skill only when the user asks for a Python backend, extends an existing Python app, or the team is Python-only. Covers OAuth auth, app resources, SQL warehouse and Lakebase connectivity, foundation-model / Vector Search / model-serving APIs (via `databricks-python-sdk`), and deployment via CLI or DABs.
Use when researching or implementing anything related to Apple platforms (iOS, iPadOS, macOS, watchOS, tvOS, visionOS), Swift/Objective-C APIs, Apple frameworks, WWDC sessions, or Apple Developer Documentation. Triggers include: "find Apple's docs", "latest API guidance", "WWDC session", "platform availability", "SwiftUI/UIKit/AppKit/Combine/AVFoundation/etc.", or any Apple SDK coding question where authoritative docs are needed. Always use the apple-docs MCP tools for discovery and citations instead of general web search.
Swift 6 and SwiftUI code rules for macOS apps, including concurrency, state, SwiftData, AppKit bridges, and fixes for common compiler errors. Use when writing, reviewing, or debugging Swift code in a Mac app, or on concurrency, Sendable, or "not in scope" errors.
Review Swift code for correctness and modern API usage. Trigger when users ask to review Swift files, report concurrency issues (DispatchQueue vs async/await), thread safety problems, logging gaps, SwiftUI anti-patterns, "Modifying state during view update" warnings, Observation feedback loops, focus/selection bugs or AppKit-interop crashes, dark mode / preview issues, performance issues, multiplatform setup problems, or project/package build-setting configuration (Swift 6 language mode, Approachable Concurrency, MainActor default isolation). Load relevant references based on the issue domain—concurrency, logging, actor isolation, project configuration, UI, observation state-mutation rules, dark mode, performance, or multiplatform configuration.
