## What it is
Few.swift is a React-inspired Swift library for building AppKit and UIKit UIs as stateless functions of their state. When state changes, it re-renders the UI and intelligently applies only the necessary view updates.

## Use cases
- build declarative macOS AppKit UIs from state
- build declarative iOS UIKit interfaces as functions of state
- avoid mutable stateful view code in Swift apps
- implement React-style unidirectional data flow in native apps
- render UIs automatically when app state changes

## When to choose
- you want React-style declarative UI in Swift on AppKit or UIKit
- you prefer immutable state-driven rendering over imperative view mutation
- you are maintaining an older Swift codebase compatible with Carthage

## When to avoid
- starting a new project, since the library is unmaintained since 2017
- you need SwiftUI or modern declarative UI support
- you need active community support or recent iOS/macOS compatibility guarantees

## Facets
- artifact type: library
