In Xcode 3, project.xcdatamodel had three panels (objects, properties, and details) at the top with a graphic thing to view your data model (diagram view). If I wanted to, for example, make my isOverdue Transient attribute, I would simply go to which of these panels has this parameter (I never did Core Data before Xcode 4) and do it with it. Xcode 4 is a pretty dramatic change from Xcode 3, and I cannot find a button or menu to do the same. The version editor allows you to view the source code, but it is blocked for editing, and I canβt imagine that this is the only option.
Google has nothing to do with any searches I can come up with, and right-clicking around it didn't help.
