Swift development for iOS/macOS with SwiftUI, async/await, and Combine. Use for .swift files.
Master Swift Package Manager - dependencies, creating libraries, publishing, local packages
Use when building a thread-safe data persistence layer in Swift using actors with in-memory cache and file storage.
Reference skill for Apple's CoreLocation framework in Swift/SwiftUI. Use this skill whenever the user works with location services, GPS, geofencing, beacon ranging, geocoding, compass headings, or any CLLocationManager-related code on iOS, macOS, watchOS, or visionOS. Trigger on mentions of: CoreLocation, CLLocationManager, CLLocation, location permissions, geofencing, CLMonitor, iBeacon, CLGeocoder, reverse geocoding, background location updates, "When In Use" / "Always" authorization, CLLocationUpdate, live updates, significant location changes, or any location-related Info.plist keys like NSLocationWhenInUseUsageDescription.
Formats xcodebuild and swift build output through xcsift into structured TOON format optimized for LLM consumption. Activates when running swift build, swift test, xcodebuild build, or xcodebuild test commands.
Automatically applies accessibility best practices to Swift projects (SwiftUI and UIKit). Use when working on iOS/macOS projects that need VoiceOver support, Dynamic Type, WCAG compliance, or accessibility audits. Triggers on Swift accessibility tasks, a11y improvements, or when the user mentions accessibility, VoiceOver, or Dynamic Type.
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.
Builds, tests, and archives Swift packages and Xcode projects for Apple platforms. Use when running xcodebuild, swift build, or swift test commands, discovering schemes and targets, or selecting simulator destinations for iOS, macOS, tvOS, watchOS, or visionOS.
Guide for building, auditing, and refactoring Swift code using modern concurrency patterns (Swift 6+). This skill should be used when working with async/await, Tasks, actors, MainActor, Sendable types, isolation domains, or when migrating legacy callback/Combine code to structured concurrency. Covers Approachable Concurrency settings, isolated parameters, and common pitfalls.
