building ReactNative application

Job ID: 30770996

Budget: $30 – $250 USD

Application is written in RN using a bunch of different RN modules. The app compiles fine for android... but when trying to compile on an actual macbook for ios it fails on OneSignal calling lFirebaseCore.
I have to mention that the current iteration of the app builds successfully using a CI/CD service, so the issue might be with local configuration files specific to mac.

Again, the app runs just fine on Android... the trouble is building on OSX for iOS.

Sample error from command line:
Ld ...../APP/ios/build/Build/Intermediates.noindex/gawq.build/Debug-iphonesimulator/OneSignalNotificationServiceExtension.appex/OneSignalNotificationServiceExtension normal x86_64

Sample error when building from xCode:
Apple Mach-O Linker failed with exit code 1. Can't find -lFirebaseCore

As this is a build error, I would like help via team-viewer connection to my mac machine, as I'd like to see your thought process and compare it to mine to better understand what's going wrong, or what I'm doing wrong.

Specs: OSX Catalina and Xcode 11.2. RN0.63.3
