Apply the Google Swift Style Guide to Swift code generation, review, and refactoring. Covers naming, file structure, formatting, and source-backed programming practices. Use for Google Swift compliance, not architecture, framework design, or project policy outside the guide.
Generate, review, or refactor Swift code using modern language features from Swift 6.0 through 6.3. Use when writing new Swift code, reviewing existing code for outdated patterns, migrating from Swift 5.x to 6.x, debugging concurrency warnings, or answering questions about current Swift idioms. Covers concurrency, typed throws, noncopyable types, observation, C interop, optimization controls, testing, and more.
