Platforms count differently and update at different times.
It starts from compiler diagnostics, actor context and enabled isolation modes, then considers main-actor isolation, guarded state, background work and valid Sendable conformance. It favors minimal behavior changes and avoids unchecked safety claims. Review edits and compile and test the project before deployment.

The counting method changed in 2026-09: skills with the same name are now counted separately by author, and the full catalog is covered. Dashed lines show months before the change; they are not compared with later months, and no growth is computed across the change.

--- name: swift-concurrency-expert description: Swift Concurrency review and remediation for Swift 6.2+. Use when asked to review Swift Concurrency usage, improve concurrency compliance, or fix Swift concurrency compiler errors in a feature or file. --- # Swift Concurrency Expert _Attribution: copied from @Dimillian’s `Dimillian/Skills` (2025-12-31)._ ## 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). - 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. Common fixes: - **UI-bound types**: annotate the type or relevant members with `@MainActor`. - **Protocol conformance on main actor types**: make the conformance isolated (e.g., `extension Foo: @MainActor SomeProtocol`). - **Global/static state**: protect with `@MainActor` or move into an actor. - **Background work**: move expensive work into a `@concurrent` async function on a `nonisolated` type or use an `actor` to guard mutable state. - **Sendable errors**: prefer immutable/value types; add `Sendable` conformance only when correct; avoid `@unchecked Sendable` unless you can prove thread safety. ## Reference material - See `references/swift-6-2-concurrency.md` for Swift 6.2 changes, patterns, and examples. - See `references/swiftui-concurrency-tour-wwdc.md` for SwiftUI-specific concurrency guidance.
