Swift Concurrency Expert
Overview
Review and fix Swift Concurrency issues in Swift 6.2+ codebases by applying actor isolation, Sendable safety, and modern concurrency patterns with minimal behavior changes.
Workflow
1. Triage the issue
- Capture the exact compiler diagnostics and the offending symbol(s).
- Check project concurrency settings: Swift language version (6.2+), strict concurrency level, and whether approachable concurrency (default actor isolation / main-actor-by-default) is enabled.
- Identify the current actor context (
@MainActor,actor,nonisolated) and whether a default actor isolation mode is enabled. - Confirm whether the code is UI-bound or intended to run off the main actor.
2. Apply the smallest safe fix
Prefer edits that preserve existing behavior while satisfying data-race safety.
