What Cannot be done with React Native?

Native iOS offers far better solutions for creating complex animations when compared to React Native. Also, if you have to use Camera, Touch ID, GPS, etc . for your app, React Native does not offer support for these. You have to use the native framework to access these features.2 Tem 2020
