概要
Provides a structured, progressive path for navigating Swift 6's strict concurrency model, moving from single-threaded defaults to advanced actor-based architectures. It helps developers resolve complex actor-isolation errors, eliminate data races, and properly utilize async/await and @MainActor attributes while ensuring UI responsiveness. By following Apple's modern guidance, the skill ensures that concurrency is introduced only when necessary, keeping codebases maintainable while leveraging background thread offloading and actor-based state management for performance-critical subsystems.
