I'm the opposite. I've done about 2.5 months of React Native now. I'm pretty certain React Native is what you want to roll with. Anything you can do in Objective-C can be done in React Native (since you can create Native modules anywhere RN falls short). You could see MAJOR improvement in development time. I'm not a mobile developer and I tried writing a mobile app a while back - I'm completely useless. With React Native, I've made huge strides in developing a fairly complex app with a completely custom look and feel. I'm sure if I had stuck to native coding I'd either never finish, or this app would take me an order of magnitude more time to complete.

If you want an example of how awesome React Native is, go check out Apple's example app "AVCam" then take a look at the example code for my react-native-camera module on GitHub.
