Swift Development Swift language-level guidance that applies across all Apple platforms. When This Skill Activates Use this skill when the user: Asks about Swift concurrency (async/await, actors, Sendable, TaskGroup) Needs help with Swift 6 strict concurrency migration Has data race or actor isolation errors Asks about InlineArray , Span , or low-level memory performance Wants to eliminate heap allocations or replace unsafe pointers Asks about modern Swift patterns independent of any specific platform Available Modules concurrency-patterns/ Swift concurrency architecture and patterns. Swift 6.2 approachable concurrency features Structured concurrency (async let, TaskGroup, .task modifier) Actors, isolation, reentrancy, @MainActor Continuations for bridging legacy APIs Swift 6 strict concurrency migration guide memory/ Swift 6.2 InlineArray and Span for low-level memory performance. InlineArray: fixed-size, stack-allocated collections with zero heap overhead Span family: safe, non-escapable access to contiguous memory Lifetime dependencies and non-escapable type constraints Performance guidance: when to use InlineArray/Span vs Array/UnsafePointer How to Use Identify user's need from their question Read relevant module files from subdirectories Apply the guidance to their specific context Cross-reference with platform-specific skills (ios/, macos/) as needed
