I am using Xcode 4.2 build 4D199. I create a new project and select the AppDelegate.h .m file and close the file. When I reopen the file I see a set of objects in the Objects Library in the Utilities panel that are either new or different. There are many more objects than usual. I'd like to use them, but when I click on either a .xib file or a storyboard file the new objects are replace by the normal old objects. Is there a way to access these new objects?
