## What it is
OpenSwiftUI is an open-source implementation of Apple's SwiftUI framework, aiming for API compatibility with the original. It targets building GUI apps on non-Apple platforms like Linux and Windows, and helps diagnose SwiftUI issues on Apple platforms.

## Use cases
- build GUI apps in Swift on Linux or Windows
- debug and diagnose SwiftUI behavior on Apple platforms
- study how SwiftUI works internally
- write SwiftUI-style declarative UI outside Apple's ecosystem
- learn SwiftUI API design through an open implementation

## When to choose
- you want SwiftUI-like declarative UI on non-Apple platforms
- you need to inspect or debug SwiftUI internals for research
- you want a learning resource for SwiftUI's API and architecture

## When to avoid
- you need a production-ready UI framework for App Store apps
- you require full SwiftUI API coverage and stability
- you cannot tolerate private API usage that may break on OS updates

## Facets
- artifact type: framework
- maturity: experimental
- function: gui, frontend-framework, ui-components, mobile-framework, desktop-framework
- domain: cross-platform, developer-tools, web-development
- platform: windows, wasm, cross-platform
- tags: swiftui, declarative-ui, apple-platforms, ui-framework, swift-package, swift, macos, ios, linux, android
