| description.long | A framework for building applications that run on Android, iOS, desktop, and web platforms, allowing developers to share code across platforms while choosing between shared UI through Compose or platform-specific native implementations | SwiftUI is Apple's declarative UI framework for creating native applications across iOS, iPadOS, macOS, watchOS, and tvOS using Swift. It simplifies UI development through straightforward syntax and integrates seamlessly with existing UIKit and AppKit code. |
