How does this skill help with Swift 6 migration?

It analyzes your project settings and provides a step-by-step strategy for enabling strict concurrency checking while providing specific code fixes for common migration errors.

Can it help fix 'Data Race' and Sendable warnings?

Yes, it identifies isolation boundaries and suggests correct implementations of Sendable, actors, or @MainActor to ensure thread safety without over-using blanket fixes.

Does it support both SwiftPM and Xcode projects?

Yes, it includes specialized tools to analyze Package.swift files and .pbxproj files to determine your specific strict concurrency and language mode settings.

When should I use this skill?

Use it whenever you are implementing async/await, refactoring legacy closure-based code, or encountering concurrency-related linter and compiler warnings.
