title: Core Data Entity Object in Object Library
body: <p>I recently downloaded Xcode 4.0. After I installed it, Xcode downloaded the Core Data Framework.  The version I have installed is 102.1. 
  I built a test application in Xcode 3.2 and was able to place a Core Data Entity in my Main Window. 
   I rewrote the application in Xcode 4.0 but cannot find a Core Data Entity in the Object Library. I am trying to discover if the Framework was not loaded properly or that for some reason is no Core Data Entity in the Xcode 4.0 Object Library. I can open my xcdatamodel file and edit it. </p>
