How does it ensure code safety during migration?

It uses a bundled migration guide to follow proven data race safety patterns and recommends verifying every change with specific compiler flags and runtime tests.

Does it support Swift Package Manager (SPM)?

Absolutely. It can analyze and modify Package.swift files to enable upcoming features like StrictConcurrency and update language mode settings.

How does this skill handle Swift concurrency warnings?

The skill identifies patterns triggering warnings, such as non-Sendable types in concurrent contexts, and proposes specific code changes like actor isolation or Sendable protocol conformance.

Can I use this for an incremental migration?

Yes, the skill follows a multi-step approach: assessing the current state, enabling warnings first, and then gradually fixing issues before enabling full Swift 6 mode.

Guides the transition of Swift codebases to Swift 6 by resolving concurrency warnings, data race issues, and enabling strict language modes.

This skill provides expert-level guidance for migrating legacy Swift projects to the Swift 6 language mode. It automates the assessment of your current codebase, identifies data race vulnerabilities, and helps implement modern concurrency patterns such as actors and Sendable conformance. By referencing a comprehensive, 25-section internal migration guide, it helps developers incrementally enable strict concurrency checking while maintaining code stability and verifying runtime behavior through integrated testing and build commands.
