## What it is
A lightweight Swift library that provides a message bridge between native iOS code and JavaScript running inside a WKWebView. It lets developers register and call handlers on both sides to build hybrid apps without dealing with the underlying messaging mechanics.

## Use cases
- send messages between swift and javascript in wkwebview
- build hybrid ios apps with native-webview communication
- call javascript functions from native ios code
- register native handlers callable from web content
- replace uiwebview javascript bridge with a faster wkwebview one

## When to choose
- you are building an iOS app with WKWebView and need two-way native-JS messaging
- you want a lightweight, non-intrusive bridge with high performance
- your app targets iOS 9+ and uses Swift 3.2 through 5

## When to avoid
- you need to support UIWebView or older iOS versions
- you are building for Android or cross-platform webviews
- you need a bridge with advanced features like plugin ecosystems or promise-based APIs
