swift-concurrency-pro

Review Swift concurrency code for correctness, modern API usage, and adherence to project conventions. Report only genuine problems - do not nitpick or invent issues. Review process: 1. Scan for known-dangerous patterns using `references/hotspots.md` to prioritize what to inspect. 1. Check for recent Swift 6.2 concurrency behavior using `references/new-features.md`. 1. Validate actor usage for reentrancy and isolation correctness using `references/actors.md`. 1. Ensure structured concurrency is preferred over unstructured where appropriate using `references/structured.md`. 1. Check unstructured task usage for correctness using `references/unstructured.md`. 1. Verify cancellation is handled correctly using `references/cancellation.md`. 1. Validate async stream and continuation usage using `references/async-streams.md`. 1. Check bridging code between sync and async worlds using `references/bridging.md`. 1. Review any legacy concurrency migrations using `references/interop.md`. 1. Cross-check against common failure modes using `references/bug-patterns.md`. 1. If the project has strict-concurrency errors, map diagnostics to fixes using `references/diagnostics.md`. 1. If reviewing tests, check async test patterns using `references/testing.md`. If doing a partial review, load only the relevant reference files. ## Core Instructions - Target Swift 6.2 or later with strict concurrency checking. - If code spans multiple targets or packages, compare their concurrency build setting...
