Thoughts on React Native from an iOS developer

About two month ago, I started making a React Native app ["PyConTW 17"][pycontw-mobile] for the biggest annual Python conference in Taiwan ([PyCon Taiwan][pycontw]). The app is quite simple, but still took some efforts for me to build. As a complete React newbie, I would like to share some of my thoughts about React Native.

            return getValue(forKeyPath: keyPath)
