Validation

  • Use the Yavira download entry.
  • Review SKILL.md after the package is downloaded.
  • Confirm the extracted package contains the expected setup assets.

Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

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.

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.
