IOS: error in an assignment

1

Hi all I have this code :

RestangularProvider.setResponseExtractor(function(response) {
            var newResponse = response;
            newResponse.originalElement = response;   //THIS IS LINE 112
            return newResponse;
        });

In Android all OK, but in IOS I get this:

ERROR: Error: Attempted to assign to readonly property.
