Master iOS development foundations - Architecture, lifecycle, memory, concurrency
Expert in the Swift ecosystem, specializing in iOS/macOS/visionOS development, Swift 6 concurrency, and deep system integration.
iOS crash-hunter skill that finds and fixes gnarly concurrency, memory, and I/O bugs using TDD. Every rule shows dangerous code, a failing test that proves the crash, and the fix that makes it pass. Complements ios-testing, swift-optimise, and other ios-*/swift-* skills. Triggers on tasks involving data races, retain cycles, deadlocks, async/await pitfalls, file corruption, thread safety, or crash debugging in Swift/iOS apps.
Generate a complete Model Context Protocol server project in Swift using the official MCP Swift SDK package.
Swift language patterns and best practices including concurrency, performance, and modern idioms. Use for Swift language-level code review or architecture guidance.
Swift modern concurrency with async/await, Task, Actor, Swift 6 strict mode, Sendable, and structured concurrency patterns.
Use when writing ANY async code, actors, threads, or seeing ANY concurrency error. Covers Swift 6 concurrency, @MainActor, Sendable, data races, async/await patterns.
Expert guidance on SwiftNIO best practices, patterns, and implementation. Use when developers mention: (1) SwiftNIO, NIO, ByteBuffer, Channel, ChannelPipeline, ChannelHandler, EventLoop, NIOAsyncChannel, or NIOFileSystem, (2) EventLoopFuture, ServerBootstrap, or DatagramBootstrap, (3) TCP/UDP server or client implementation, (4) ByteToMessageDecoder or wire protocol codecs, (5) binary protocol parsing or serialization, (6) blocking the event loop issues.
Thread-safe data persistence in Swift using actors — in-memory cache with file-backed storage. Use when building local storage layers, offline-first patterns, or any shared mutable state that needs both concurrency safety and disk persistence.
Comprehensive macOS app development with Swift 6.2, SwiftUI, SwiftData, Swift Concurrency, Foundation Models, Swift Testing, ScreenCaptureKit, and app distribution. Use when building native Mac apps, implementing windows/scenes/navigation/menus/toolbars, persisting data with SwiftData (@Model, @Query,
Build, review, or improve Core Data persistence in apps that have not adopted SwiftData. Use when working with NSManagedObject subclasses, NSFetchedResultsController for list-driven UI, NSBatchInsertRequest / NSBatchDeleteRequest / NSBatchUpdateRequest for bulk operations, NSPersistentHistoryChangeRequest for persistent history tracking and multi-target sync, NSStagedMigrationManager for staged schema migrations (iOS 17+), NSCompositeAttributeDescription for composite attributes (iOS 17+), or when integrating Core Data threading with Swift Concurrency. For Core Data + SwiftData coexistence or migration, see the swiftdata skill instead.
Timer, DispatchSourceTimer, Combine Timer.publish, AsyncTimerSequence, Task.sleep API reference with lifecycle diagrams, RunLoop modes, and platform availability
