Is there a problem in Xcode?

where to put "source="$(readlink -f "${source}")"" exactly I have replaced it with APPNAME/ios/App/Pods/Target Support Files/Pods-App/Pods-App-frameworks.sh under build phases "[CP] Embed Pods Frameworks" but still not able to build and when i run pod install or update it returns the original one.
