Cannot find type 'ConfigurationIntentHandling' in scope

My main project is developed using Object-c. When I choose to use Intents, when I transfer data from the main project to the IntentHandler, the following errors occur 1. Cannot find type'ConfigurationIntent' in scope 2. Cannot find type'Members 'in scope

Any luck finding the problem? I am having a very similar problem.
