swift-expert
Complete iOS/macOS/watchOS/tvOS development with SwiftUI, async/await, protocol-oriented design, and actor-based concurrency.
- Covers SwiftUI state management with @Observable, async/await patterns, protocol-oriented architecture with associated types, and actor isolation for thread safety
- Includes validation checkpoints at each workflow stage: compilation verification, strict warning checks for actor isolation, and async test confirmation
- Provides reference guides for SwiftUI patterns, concurrency, protocol design, memory management, and testing strategies with XCTest
- Enforces Swift API Design Guidelines, Sendable compliance, value-type semantics, and comprehensive error handling across all implementations
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 buildto verify compilation. After step 4, runswift build -warnings-as-errorsto surface actor isolation and Sendable warnings. After step 5, runswift testand confirm all async tests pass.
