react native xcode error | ld: library not found for -lAppAuth

Question

i have been struggling with this for almost 2 weeks. here is the error:

ld: warning: directory not found for option '-L-L/Users/carrabre/Library/Developer/Xcode/DerivedData/imbue-dvxkstblumxsdqhbfwsepkllnggv/Build/Products/Debug-iphonesimulator/AppAuth'
ld: library not found for -lAppAuth
clang: error: linker command failed with exit code 1 (use -v to see invocation)

this happens when building in xcode & from the command line in VSCode. i have tried deleting derived data, reintegrating pods, updating pods, factory resetting my computer, making sure my linker files are set up, build active architecture to yes. i would appreciate any help! here is the error logs

running xcode Version 12.0.1 (12A7300) & mac OS catalina 10.15.7

This looks like the "double -L" problem I've seen other places. This solution seems to work for a lot of people: https://github.com/react-native-community/upgrade-support/issues/36#issuecomment-611516268, i.e.

Go to the project "Build Settings", find "Library Search Paths", and make sure $(inherited) is there. Per the above GitHub, you may need to move it to the top of the list.
