Custom class not shown in storyboard identification inspector

I created a new class in my application with the name EmpresasTableViewController, and in the storyboard I copied it CategoriasViewControllerto EmpresasTableViewController, I just want to assign the class EmpresasTableViewController EmpresasTableViewControllerin the storyboard, but the name EmpresasViewControllerdoes not appear in Identity Inspector.

After creating the class, there are no errors, but why is it not shown as a class in the storyboard Identity Inspectorunder Custom Class?, all other view managers are displayed.
