Sick and tired of building native iOS and Android UIs? React Native makes the tweak-compile-run-test loop much tighter than with the native SDKs. In this talk, David Kay will give us an overview of the React Native toolchain and show us how developers can up their game through the use of interactive tools. NOTE: A large piece of this talk is the live demo of an interactive drag-and-drop UI builder for React Native. Please watch www.proreactnative.com for its release.
