## What it is
Cacao is a pure Swift cross-platform reimplementation of UIKit (Cocoa Touch) that runs on macOS and Linux. It lets Swift developers build GUI applications with familiar UIView-based APIs outside of Apple platforms, backed by SDL2 and Cairo.

## Use cases
- build a UIKit-style GUI app on Linux
- run PaintCode StyleKits on Linux
- create cross-platform Swift desktop applications
- use UIView animations outside iOS
- render vector graphics with UIKit APIs on macOS and Linux

## When to choose
- you know UIKit and want to build Linux or macOS GUIs in Swift
- you need to port iOS-style view code to non-Apple platforms
- you want hardware-accelerated UIView animations in a native window manager

## When to avoid
- you need a production-ready, fully compatible UIKit implementation
- you are targeting iOS or native App Store apps
- you need a mature widget toolkit with broad platform support

## Facets
- artifact type: framework
- maturity: experimental
- function: ui-components, graphics, gui
- domain: cross-platform, developer-tools, graphics
- platform: cross-platform
- tags: uikit, cocoa-touch, swift, vector-graphics, sdl2, cairo, linux, macos
