## What it is
TwUI is a hardware-accelerated UI framework for macOS built on Core Animation and inspired by UIKit, offering familiar model/view/controller development for iOS developers. It was used in Twitter for Mac but is an archived alpha project with no recent releases.

## Use cases
- build a GPU-accelerated Mac UI with UIKit-like APIs
- port iOS development patterns to macOS apps
- render custom table views with Core Animation
- mix TwUI views into an existing AppKit application
- learn how a UIKit-inspired framework works on the Mac

## When to choose
- you maintain a legacy Twitter for Mac codebase or study historical UI framework design
- you want UIKit-style development on macOS and accept an unmaintained library

## When to avoid
- you need a maintained, modern macOS UI toolkit - use SwiftUI or AppKit
- you require accessibility support or full text editing features
- you need AppKit views embedded inside TwUI views

## Facets
- artifact type: framework
- maturity: abandoned
- function: ui-components, graphics, animation
- domain: desktop-applications, web-development
- platform: cpp
- tags: core-animation, uikit-inspired, objective-c, gpu-accelerated, archived, mac, macos
