React Native vs Swift/Objective-C/Java Native

I'm working on a new project for a Fintech company and I have been tasked with looking into whether we should go with React Native or native Swift/Objective-C/Java for our mobile app development technology and strategy going forward.

I have done loads of research into this and have read many of the case studies relating to React Native, but I still don't feel I have enough to make an informed decision at this point.

The broad app functionality will include things like:

Data related functions such as Account Balances and Statements (pretty simple)
Image capture of identity documents and selfies of the users
Capture of biometric data
Push notifications

Some of this is pretty standard and simple, but some of it will require the app to use low level device functions and/or use 3rd party Android and iOS SDKs.

So, in terms of working towards the decision of a mobile development strategy, can I ask you for your input, based on your recent experience, on reasons to consider React Native over native Swift/Objective-C/Java development in the light of the planned functionality listed above (including reasons why it may be far better to stick with the native languages/platforms).

Solution

React Native has a really nice and tempting idea behind sounds like "unified and almost fully shareable codebase for different platforms including Web". But from my experience (not so extensive but still) the reality is a little bit different – at some point you will face some issues with native code for sure, and it would be really good if you have experienced Swift/Objective-C/Java developers in your team to deal with it. Don't trust the promises "all you need is just a React Front-End Developer". The React Native platform itself seemed to me more like a magical blackbox which I ran with a single command having no any idea what's inside and how it actually works. You have to know at least something about Xcode and Android Emulator even if Facebook is trying to hide this aspect it from you as much as they can.

TL;DR In my opinion if you really want to try React Native for something more complex than TodoMVC then you need to have at least 3 developers: Web (JavaScript/React), iOS (Swift/Objective-C) and Android (Java). Or just one Superhero.
