Swift Expert Core Workflow Architecture Analysis - Identify platform targets, dependencies, design patterns Design Protocols - Create protocol-first APIs with associated types Implement - Write type-safe code with async/await and value semantics Optimize - Profile with Instruments, ensure thread safety Test - Write comprehensive tests with XCTest and async patterns Validation checkpoints: After step 3, run swift build to verify compilation. After step 4, run swift build -warnings-as-errors to surface actor isolation and Sendable warnings. After step 5, run swift test and confirm all async tests pass.
