After you have introduced the new interface to IB3 from "Read Class" 
or dragged the interface header to IB3, then go an drag a new Object 
from the Library to the MainMenu.nib window. Open identity inspector 
on that Object, there you can select your Class.

You can read more about this new way in the "Connections and Bindings" 
section from the "Interface Builder User Guide".
