## What it is
NUI is a drop-in UI kit for iOS that lets developers style UIKit elements using a CSS-like stylesheet with Sass/LESS-style variables. It enables restyling an entire Objective-C iOS app through simple declarative rules instead of programmatic appearance code.

## Use cases
- style ios app with a css-like stylesheet
- apply a consistent theme across an entire ios app
- define reusable style variables like fonts and colors for uikit
- restyle buttons and navigation bars without touching code
- share themes between multiple ios applications

## When to choose
- you maintain a legacy Objective-C iOS app and want centralized, stylesheet-driven theming of UIKit elements
- you want to restyle an entire app quickly by editing a single CSS-like file
- you want Sass/LESS-style variables for iOS UI styling

## When to avoid
- you are starting a new project in Swift with SwiftUI or modern UIKit appearance APIs
- you need actively developed theming with current iOS feature support
- you need cross-platform styling across Android and iOS

## Facets

- maturity: maintenance
- function: ui-components, css-framework, theme
- domain: mobile-development, frontend, web-design
