 ## Platforms Supported
 
-- [x] iOS (both UIWebView and WKWebView)
+- [x] iOS
 - [x] Android
 
 _Note: Expo support for React Native WebView started with [Expo SDK v33.0.0](https://blog.expo.io/expo-sdk-v33-0-0-is-now-available-52d1c99dfe4c)._
 Current Version: ![version](https://img.shields.io/npm/v/react-native-webview.svg)
 
 yarn add react-native-webview@androidx
+
 - [6.0.**2**](https://github.com/react-native-community/react-native-webview/releases/tag/v6.0.2) - Update to AndroidX. Make sure to enable it in your project's `android/gradle.properties`. See [Getting Started Guide](docs/Getting-Started.md).
 
 yarn add react-native-webview
+
 - [5.0.**1**](https://github.com/react-native-community/react-native-webview/releases/tag/v5.0.0) - Refactored the old postMessage implementation for communication from webview to native.
 - [4.0.0](https://github.com/react-native-community/react-native-webview/releases/tag/v4.0.0) - Added cache (enabled by default).
 - [3.0.0](https://github.com/react-native-community/react-native-webview/releases/tag/v3.0.0) - WKWebview: Add shared process pool so cookies and localStorage are shared across webviews in iOS (enabled by default).
 
 **Upcoming:**
 
-- UIWebView removal
 - this.webView.postMessage() removal (never documented and less flexible than injectJavascript)
 - Kotlin rewrite
 - Maybe Swift rewrite
 
 ## Common issues
 
-- If you're getting `Invariant Violation: Native component for "RNCWKWebView does not exist"` it likely means you forgot to run `react-native link` or there was some error with the linking process

 ## Notes
 
 - We use TypeScript.
-- We don't intend to support UIWebView and will remove it soon.
 - After pulling this repo and installing all dependencies, you can run tests using the command: `yarn ci`

docs/Custom-iOS.md

 If you open webpages that needs a Client Certificate for Authentication, you can create a credential and pass it to the webview:
 
 ```
-[RNCWKWebView setClientAuthenticationCredential:credential];
+[RNCWebView setClientAuthenticationCredential:credential];
 ```
 
 This can be paired with a call from Javascript to pass a string label for the certificate stored in keychain and use native calls to fetch the certificate to create a credential object. This call can be made anywhere that makes sense for your application (e.g. as part of the user authentication stack). The only requirement is to make this call before displaying any webviews.
