Cheat Sheet
`@State var name: String` - reactive state variable
`Text(name)` - display reactive value
`VStack { ... }` - vertical layout container
`List(data) { item in ... }` - dynamic list
`.animation(.default)` - add animation to view

Frequently Asked Questions about Swiftui
What is Swiftui?
SwiftUI is Apple’s declarative framework for building user interfaces across iOS, macOS, watchOS, and tvOS using Swift. It allows developers to create fully native apps with less code and real-time previews.
What are the primary use cases for Swiftui?
Native iOS apps with modern UI. macOS desktop apps. watchOS and tvOS apps. Rapid prototyping for Apple platforms. Apps leveraging Swift ecosystem and Apple frameworks
What are the strengths of Swiftui?
Fully native performance. Single codebase across Apple platforms. Minimal boilerplate code with declarative approach. Tight integration with Swift and Apple frameworks. Live preview and hot reload speeds up development
What are the limitations of Swiftui?
Apple platforms only, not cross-platform outside Apple. Requires Swift knowledge. Some complex UI components require UIKit fallback. Limited backward compatibility (iOS 13+). Smaller ecosystem compared to UIKit/React Native for some features
How can I practice Swiftui typing speed?
CodeSpeedTest offers 9+ real Swiftui code examples for typing practice. You can measure your WPM, track accuracy, and improve your coding speed with guided exercises.
