I have upgraded the reactnative from 0.61 to 0.63 using upgrade helper now I'm facing this issue while running react-native run-ios.
ld: symbol(s) not found for architecture x86_64 clang: error: linkercommand failed with exit code 1 (use -v to see invocation)
- BUILD FAILED *
The following build commands failed:Ld /Users/sshah/Library/Developer/Xcode/DerivedData/newapp-ggwouaubanbpyhgaxauunijgwgmj/Build/Products/Debug-iphonesimulator/newapp.app/newappnormal x86_64 (1 failure).
Any possible solution to try.Thanks
