React Native + Expo is also a good option if you want to touch the iOS/Android IDEs as little as possible. You use Xcode and Android studio to install the device sims and then expos tool chain handles the rest, even for deploying to stores. If you are on a windows computer and can’t install Xcode, you can even run your iOS app directly on an iPhone with their managed app.
Ignite is a great starter using RN and Expo. Some great people maintaining it. https://github.com/infinitered/ignite
