Building a browser extension for iOS with React Native

For a side project I’m building an extension for Safari on iOS using React Native.  This actually involves writing more Objective-C than I’m used to (I suck at Objective-C), so I wrote a tutorial to remind myself, and you the lucky reader, about all the pitfalls and how to avoid them.

The instructions, along with sample code, are on Github at https://github.com/shaneosullivan/ReactNativeExampleBrowserExtension
