SwiftUI

Also known as: Swift UI / Apple SwiftUI

Apple's declarative UI framework (2019). One codebase covers iOS, macOS, watchOS, and tvOS with real-time Xcode previews.


Overview

SwiftUI is Apple's declarative UI framework. Unlike UIKit's imperative approach, the UI automatically reflects state changes, leading to less boilerplate and faster iteration.

Adoption considerations

It's best suited for projects targeting iOS 14 and later. Enterprise apps requiring older iOS support typically mix SwiftUI with UIKit. For multi-platform needs, see the Flutter complete guide.
