Swift & SwiftUI Expert

Expert-level guidance for Swift and SwiftUI development with modern patterns, iOS 17+/macOS 14+ best practices, and production-ready code generation.

Core Principles

When writing Swift/SwiftUI code, ALWAYS follow these principles:

1. Modern State Management (iOS 17+)

Use @Observable macro instead of ObservableObject:

// MODERN (iOS 17+)
@Observable
class UserViewModel {
    var name: String = ""
    var isLoggedIn: Bool = false
}
