问题
I wanted to test firebase initial app on Unity. I made a build from Unity in macOS and in Xcode project folder, I have runned the pod command successfully.
pod install
After this I opened Xcode project and I clicked to build button. Before this, I was getting framework not found error. I fixed it and now I am getting
ld: warning: directory not found for option '-L/Users/ali/Library/Developer/Xcode/DerivedData/Unity-iPhone-giljorflztrrychfchrkhcfbqtbh/Build/Products/ReleaseForRunning-iphoneos/FirebaseAuth'

ld: library not found for -lFirebaseAuth
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I have already added library pathes to library search path. I added some screenshots as attachments.
回答1:
I solved the error by opening ".xcworkspace" file, instead of ".xcodeproj" file.
