List production-ready SwiftUI code recipes. Each recipe is a complete, copy-paste-ready implementation — not a tutorial. Covers native iOS features (SwiftUI, Swift Charts, SpriteKit, Vision, AVFoundation, StoreKit 2, NavigationStack) and backend infrastructure (AWS CDK, Hono, Node.js, Cognito, DynamoDB). Categories: animations, charts, UI components, and full-stack modules including auth, camera, subscriptions, chat, and settings.
