Hello,
This is Louis. I was running out of hard drive space in MacBook. I bought a removal drive and move all my files and including xcode there. Here is the error that I have been getting:
/Volumes/Mac Extension/FetalGrowthPercentile/Pods/FirebaseAuth/FirebaseAuth/Sources/AuthProvider/Phone/FIRPhoneAuthProvider.m:20:9: Did not find header ‘Sources/Public/FirebaseAuth/FIRAuthSettings.h’ in framework ‘FirebaseAuth’ (loaded from ‘/Users/littlemathematician/Library/Developer/Xcode/DerivedData/FetalGrowthPercentile-byygvcbyszmotwdwyjqbnpugaypf/Index/Build/Products/Debug-iphonesimulator/FirebaseAuth’)
Please Help!
