Ionic Cordova Build --Prod flag not working in iOS Xcode 10

While executing ionic cordova build command with --prod flag gives compiler erros in iOS xCode 10 environment, When I raised this in [cordova-ios] group https://github.com/apache/cordova-ios/issues/446 they said it is ionic specific issue, hence I am posting here. Please suggest.


ionic cordova build ios --release --prod – --buildFlag="-UseModernBuildSystem=0"

Below compiler error I am getting while executing above command in MAC with xCode 10

74-80-250-211:ios user913708$ [ERROR] An error occurred while running subprocess ionic-app-scripts.

-bash: [ERROR]: command not found

74-80-250-211:ios user913708$ ionic-app-scripts build --prod --target cordova --platform ios exited

    with exit code 1.

    

    Re-running this command with the --verbose flag may provide more 

    information.[12:36:57]  ionic-app-scripts 3.2.0

Are you able to build for Android?

Can you reproduce the problem and share the repo? Happy to try locally.

There is absolutely no such build issues with the Android. Below compiler error I am getting while executing the ionic cordova build ios --release --prod – --buildFlag="-UseModernBuildSystem=0"

syntax error near unexpected token `newline'
