Covers Swift 6 language and platform fundamentals shared across iOS, macOS, iPadOS, watchOS, and visionOS: async/await and actors with strict concurrency checking, Sendable typing, app architecture (MVVM with @Observable as the recommended default, Clean Architecture for complex apps), async testing with XCTest, String Catalog-based localization, and performance profiling with Instruments. References cover each area in depth: concurrency, architecture/DI, testing, i18n, and performance. Best practices: prefer actors over classes with locks for shared state, @Observable over ObservableObject, structured concurrency over completion handlers, String Catalogs for all user-facing text, profiling in Release (-O) builds, and value types (structs) over classes where possible. Swift 6 fundamentals shared across all Apple platforms. Before ANY implementation, spawn 3 agents in parallel, one Agent call each with a name: 1. fuse-ai-pilot:explore-codebase - Analyze existing Swift patterns 2. fuse-ai-pilot:research-expert - Verify latest Swift 6 docs via Context7/Exa 3. mcpapple-docssearchappledocs - Check Swift concurrency patterns After implementation, run fuse-ai-pilot:sniper for validation.
