React Native 0.66 iOS crashes on AppDelegate RCTRootView init - ios

Question

I'm trying to upgrade our RN project to 0.66 (from 0.63). When I build the project in debug mode, the app crashes on startup due to uncaught exception 'NSInvalidArgumentException', reason: '-[REAEventDispatcher setBridge:]: unrecognized selector sent to instance 0x600002f51cc0' when initializing the RCTRootView in the AppDelegate.m file (entire file at the end).
After some googling, I found the unrecognized selector bit is because some function is undefined on an object. The error is marked in the code, its about halfway through the file.
I need some help finding out why this function isn't available (or what else is wrong). As far as I can see, the files have an implementation of the functions that are called. Am I missing any imports? Not that well versed in Swift, only used it in combination with React Native.
I haven't made a reproducible example, but I hope someone else has come over this already in porting to this version. If you need any more information, please ask. I've also attached the podfile below the relevant file.

Answer 1

As jnpdx pointed out, I needed to follow the upgrade helper. Turns out there were quite a few steps I had missed doing it without it.

Answer 2

For me I had the iOS Deployment target under build settings on 9, while on the Podfile on 11. Changing to 11 solved the problem, see how to change iOS Deployment target. Also, remember to npx react-native-clean-project
