Background: I worked on the NFL mobile app and then worked on a search engine app both of which were in React Native. Specifically I worked on the team that did the developer tooling side for other teams. I made it so experienced JavaScript developers who had no experience with native mobile could create features more easily. Both get millions of downloads.

React Native is a pain to work with when the scope of your app becomes any larger than an agency level project (e.g. an app for an event that's only going to be used one weekend).

Once you start getting into requirements for a prime time production app (setting up APM tool, setting up tracking, setting up Google Analytics, native specific features that don't have a React Native hook yet) React Native is an extra layer of abstraction that slows you down. The experienced native developers hate working with it because they'd rather just use the related native platform themselves, but at the same time for any slightly complicated app you still need their expertise. Also, out of the box animations in React Native is difficult to work with, especially with less experienced developers, so you end up having to do a variety of work arounds to get animations between screens to look nice which you'd get out of the box just using Kotlin/Swift.

In 2020 if I needed to make an app quickly, cheaply, that worked on both platforms, I'd make a great mobile website and wrap it in a native shell. Any screen that needed a little bit extra "magic" I would do 100% native code for both platforms. This also allows you to ship updates to screens as you go without a complicated "codepush" JavaScript setup, as it's just a webview on the other end.

I'm still maintaining the React Native search app now, it works fine, but if we need to create an iOS version of it I'd definitely pitch doing it in native code.

I’ve just been building an app using react native (for web). We built the web app first and had it responsive and designed to match mobile interactions from the start (a stack view that keeps state) and it’s been quite nice. The other day went to get it running on native and was pleasantly surprised - was able to get all the main screens working smoothly and well in a matter of days.

Compared to SwiftUI it was far easier and even faster. Granted, I’ve worked with React a lot. But it’s really quite nice, I’m impressed with the whole ecosystem and how it’s grown.
