concurrency▌

Purpose: Progressive journey from single-threaded to concurrent Swift code Swift Version: Swift 6.3 (strict concurrency by default). @concurrent requires Swift 6.2+. iOS Version: iOS 17+ (iOS 26+ for @concurrent) Xcode: Xcode 16+ (Xcode 26+ for @concurrent)

Swift concurrency code reviewer that catches reentrancy bugs, isolation violations, and async/await pitfalls. \n \n Scans for dangerous patterns across actors, structured/unstructured tasks, cancellation handling, and async streams using a 12-step review process \n Targets Swift 6.2+ with strict concurrency checking, comparing build settings across multiple targets when needed \n Prioritizes structured concurrency (task groups) over unstructured tasks and async/await over closure-based APIs and

Production patterns for Go concurrency including goroutines, channels, synchronization primitives, and context management. \n \n Covers core primitives: goroutines, channels, select, sync.Mutex, sync.WaitGroup, and context.Context with practical examples for each \n Includes seven battle-tested patterns: worker pools, fan-out/fan-in pipelines, bounded concurrency with semaphores, graceful shutdown, error groups, concurrent maps, and select timeouts \n Provides race detection guidance via command
