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
