Summary
A comprehensive reference for modern Swift development that covers the big shift to Swift 6's concurrency model. Focuses on actors, async/await, MainActor isolation, and Sendable conformance with practical patterns for avoiding data races. Integrates with the SwiftLens MCP server to combine semantic code analysis with design guidance. Includes migration advice for Swift 5 codebases, API naming conventions following Apple's guidelines, and coverage of breaking changes in Swift 6. Genuinely useful if you're writing production Swift for iOS or macOS and need to navigate the stricter concurrency checking without fighting the compiler. The examples are clear and show both what to do and common pitfalls to avoid.
