Swift concurrency

Current Swift concurrency guidance for implementation, review, and migration work.

Skills

Skill	Purpose
swift-concurrency	Write code with strict isolation, Sendable, tasks, actors, and current language behavior.
swift-concurrency-review	Audit code for traceable concurrency defects and report them by severity.
swift-concurrency-migration	Inspect a codebase and plan staged adoption of strict concurrency.

References cover actor patterns, feature flags, GCD migration, Sendable work, SwiftUI, and Swift 6.3 to 6.4 changes. Runnable examples live under skills/swift-concurrency/examples/.

The generated Claude Code adapter keeps /swift-audit, concurrency-reviewer, and swift-migration-planner as thin wrappers around the portable skills.
