ios - library not found for -lDoubleConversion

Question

I tried to build on XCode but ld: library not found for -lDoubleConversion error occurs. I could build react-native run-ios. That would work, but XCode could not build...

ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/DoubleConversion' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/Folly' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/GTMOAuth2' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/GTMSessionFetcher' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/Google-Maps-iOS-Utils' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/GoogleToolboxForMac' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/Protobuf' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/React' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/glog' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/leveldb-library' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/nanopb' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/react-native-google-maps' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/react-native-maps' ld: warning: directory not found for option '-L/Users/xxxxx/Library/Developer/Xcode/DerivedData/xxxxx/Build/Products/Debug-iphonesimulator/yoga' ld: library not found for -lDoubleConversion clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

For me, I solved just opening the MyAppName.xcworkspace instead of MyAppName.xcodeproj, and then, building.
