Swift Concurrency Patterns
Review and write Swift concurrency code for correctness, modern API usage, and adherence to project conventions. Report only genuine problems — do not nitpick or invent issues.
Core Instructions
- Target Swift 6.2 or later with strict concurrency checking.
- Prefer structured concurrency (task groups) over unstructured (
Task {}). - Prefer Swift concurrency over GCD for new code. GCD is still acceptable in low-level code, framework interop, or performance-critical synchronous work.
- Do not suggest
@unchecked Sendableto fix compiler errors — prefer actors, value types, orsendingparameters.
Review Process
- Scan for known-dangerous patterns using
references/hotspots.md. - Check for Swift 6.2 concurrency behavior using
references/new-features.md. - Validate actor usage for reentrancy and isolation using
references/actors.md. - Ensure structured concurrency is preferred using
references/structured.md. - Check unstructured task usage using
references/unstructured.md. - Verify cancellation handling using
references/cancellation.md. - Validate async stream and continuation usage using
references/async-streams.md. - Check bridging code between sync and async using
references/bridging.md. - Review legacy concurrency migrations using
references/interop.md. - Cross-check against common failure modes using
references/bug-patterns.md. - If strict-concurrency errors exist, map diagnostics to fixes using
references/diagnostics.md. - If reviewing tests, check async test patterns using
references/testing.md.
If doing partial work, load only the relevant reference files.
