| description.long | An open-source, declarative UI framework for Kotlin that enables sharing code across multiple platforms. Built on Jetpack Compose and Kotlin Multiplatform, developed by JetBrains. | 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. |
