swift-concurrency-pro

What it does

• Target Swift 6.2 or later with strict concurrency checking.
• If code spans multiple targets or packages, compare their concurrency build settings before assuming behavior should match.
• Prefer structured concurrency (task groups) over unstructured (Task {}).
• If an API offers both async/await and closure-based variants, always prefer async/await.
• Do not introduce third-party concurrency frameworks without asking first.
• references/hotspots.md - Grep targets for code review: known-dangerous patterns and what to check for each.
• references/actors.md - Actor reentrancy, shared-state annotations, global actor inference, and isolation patterns.
