## What it is
Bond is a Swift binding framework built on ReactiveKit that enables type-safe, reactive bindings between UI components and state. It bridges reactive and imperative paradigms for iOS development with observable property extensions for UIKit components.

## Use cases
- bind a text field to a label in ios
- observe uikit control events reactively
- simplify state changes with bindings in swift
- build mvvm apps with reactive data sources
- transform ui input streams with functional operators

## When to choose
- you want declarative data binding for UIKit in Swift
- you already use ReactiveKit and want bindings on top
- you prefer reactive delegates and data sources over target-action

## When to avoid
- you are building with SwiftUI and Combine instead of UIKit
- you need a framework with frequent updates and active maintenance
- you want a cross-platform reactive solution beyond Apple platforms

## Facets
- artifact type: framework
- maturity: maintenance
- function: state-management, ui-components
- domain: mobile-development, frontend
- platform: -
- tags: reactive-programming, data-binding, reactivekit, uikit, mvvm, ios, swift, mobile
