Core module not found on iOS & nanopb error

Issue

I've got an issue I've been banging my head against. I get two errors on a new install for Core. I believe I've followed the instructions, tried to mimic the starter template, and read through the docs. Could absolutely be user error but I'm running into a wall.

1. I get the RNFirebase core module was not found error in the simulator.

2. I get a build failed message in Xcode and while trying react-native run-ios that has to do with nanopb

** BUILD FAILED **
The following build commands failed:

LocalPath/ios/build/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/nanopb.build/Objects-normal/x86_64/nanopb-dummy.o Target\ Support\ Files/nanopb/nanopb-dummy.m normal x86_64 objective-c com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)

It looks like the following in Xcode:

My Podfile

Things I have tried:

• Cleaning the project, quitting Xcode, cleaning the project again and trying to build
• Deleting all the pods / reinstalling / running pod update and pod install more times than I'd like to admit
• Set weak references to yes and explicitly set the iOS deployment target

I'm running out of ideas. Anyone seeing something similar? Admittedly, I'm newer to React Native / iOS development. Am I overlooking something simple?

Update. I've managed to fix the core module not found error. I followed the troubleshooting guide from Cocoapods docs. I had to go to Product --> Edit Scheme --> Build, add the Pods static library, drag them to the top of the list, clean and then rebuild.

Still wrestling with the build failure error from nanopb.

Was able to get the nanopb issue solved after reading this issue

Nanopb has the iOS deployment target set to 4.3 by default. If you bump it up to 9.0, it solves the error.
