When should I use this skill?

Use it whenever you are writing asynchronous code, dealing with multi-threading, managing shared state, or encountering compiler warnings related to concurrency in Swift.

Can it fix data races in my existing code?

Yes, the skill analyzes your code's isolation boundaries—such as actors, global actors, and nonisolated contexts—to suggest the safest fixes for data race warnings.

Does it support both Xcode and Swift Package Manager projects?

Absolutely. The skill includes specific procedures to detect concurrency settings and upcoming feature flags in both .pbxproj and Package.swift files.

How does this skill help with Swift 6 migration?

It provides step-by-step guidance on enabling strict concurrency checking, resolving Sendable errors, and managing isolation boundaries to meet the safety requirements of the Swift 6 language mode.
