Things I’ve done to figure out my issue

• I used upgrade-helper to do my upgrade.

Upgrading version

From 0.70.6 to 0.71.4

Description

After upgrading everything as described in the RN Upgrade Helper Guide, even though I have entirely deleted my node_modules, yarn.lock, cleaned/deleted everything related to the Pods, I’m not able to build successfully my app with the following issue being presented on Xcode:

'RCTAppDelegate.h' file not found

Here is what’s inside my AppDelegate.h:

#import <RCTAppDelegate.h>
#import <UIKit/UIKit.h>

@interface AppDelegate : RCTAppDelegate

@end

Reproducible demo

Unfortunately I can’t recreate a reproducible demo for this app. Just one thing that might help is that I’m currently using the react-native-firebase lib which asks me to do some changes in some iOS files as described here these are just the difference that my app has regarding the iOS files. Other than that, all looks the same as the Upgrade Guide.
