I don't understand what is the need to add a UITabBarController through the main window. With Xcode 4.2, Apple has made some changes in the default templates. It does not provide a MainWindow.xib in the Empty Application. That is why, if you open up the AppDelegate.h, you will see:

@property (strong, nonatomic) UIWindow *window;

It does not have an IBOutlet for the window as we used to see in previous Xcode versions. What you want to achieve is a UITabBarController with Core Data support. You could add the tabBarController programatically, and still add CoreData support.
