Swift Expert

Handles the full Swift stack from iOS to server-side with a strong bias toward modern idioms: @Observable over ObservableObject, actors instead of manual locks, protocol-oriented design from the start. The workflow pushes you through architecture analysis before implementation, with validation checkpoints that catch actor isolation warnings as errors. Code patterns show correct async/await usage, SwiftUI state management with Swift 5.9+ features, and repository protocols with associated types. Useful if you're working in Swift 5.9 or later and want guardrails that steer you away from legacy patterns. The reference guide structure assumes you'll load topic-specific docs on demand rather than dumping everything upfront.
