SwiftUI is a user interface framework[1] for building user interfaces for iOS, iPadOS, watchOS, tvOS, visionOS and macOS, developed by Apple Inc. for the Swift programming language. It was announced at the company's Worldwide Developers Conference (WWDC) on June 3, 2019.

SwiftUI is declarative, contrasting with the imperative syntax used in other Apple development frameworks such as UIKit and AppKit. SwiftUI allows for interoperability with other UIKit views, 2D drawing, animations, event handling, widgets, and data binding. SwiftUI automatically synchronizes between UI views and data.[2]

SwiftUI integrates with other Apple services, such as Xcode to provide for real-time previews during editing,[3] and support for maps with Apple Maps.[4]
