migrating-to-swift-concurrency

What it does

This skill provides a comprehensive guide for migrating existing Swift codebases to Swift Concurrency. It covers the process of upgrading to Swift 6, addresses and resolves potential data-race safety issues that arise during migration, and explains the principles behind Sendable and actor isolation. The guide facilitates an incremental adoption approach, allowing developers to transition gradually.

When to use it

• Swift 6 Upgrade: You're preparing your project for Swift 6 and need assistance with concurrency-related changes.
• Data Race Resolution: Your code is flagged with data-race safety errors during compilation or testing.
• Understanding Isolation: You want a deeper understanding of Sendable protocols and how actors enforce isolation.
• Incremental Adoption: You prefer to introduce Swift Concurrency features in stages rather than a complete rewrite.

Key capabilities

• Complete Swift Concurrency Migration Guide
• Data-race safety error resolution
• Explanation of Sendable protocol
• Actor isolation principles
• Incremental adoption strategy

Example prompts

• "Guide me through migrating my existing dispatch queue code to actors."
• "How do I resolve a data-race safety error related to shared mutable state?"
• "Explain the difference between Sendable and awaiting in Swift Concurrency."

Tips & gotchas

The guide assumes familiarity with basic Swift programming concepts. Successfully migrating requires careful consideration of how shared mutable state is handled within your codebase, as this is a common source of data-race issues.
