Build fluid and engaging declarative UI for your apps — using less code — with SwiftUI! With SwiftUI, you can define what your app’s UI should do with concise, declarative language, and say goodbye to tons of confusing UIKit code. Build modern, responsive UI and animations that look great on iOS, iPadOS, watchOS, tvOS or even macOS! SwiftUI is a new paradigm in Apple-related development. SwiftUI’s introduction in 2019 creates another opportunity for a paradigm shift in the industry. After years using UIKit and AppKit to create user interfaces, SwiftUI presents a fresh, new way to create UI for your apps. IN many ways, SwiftUI is much simpler and powerful than its predecessors, and even more importantly, it’s crossplatform over the Apple ecosystem.
