title: Xcode 4.2 Interface Builder Dock Icons
body: <p>I've been trying to complete some basic tutorials to familiarize myself with UIViews and ViewControllers, but some tutorials I see ask me to select an "<em>app name</em> App Delegate" icon in the dock (just left of the Interface Builder panel).  I'm seeing the icons for Placeholders: "File's Owner", "File's Responder" and icons for the Objects I've added to my view, but no icon for an App Delegate.  </p>
  
  <p>This is using an iOS Empty Application and not any other template when creating a new project and I'm basically trying to connect my App Delegate's rootViewController outlet to a view Controller in a nib file.</p>
  
  <p>Has this icon been removed from XCode 4.2?  Is it somewhere else or can be accessed in a different way? I'm guessing a lot of my confusion is because I'm referencing tutorials that came before XCode 4.2 and the new iOS 5 SDK.  I'm really new to XCode and iOS in general and the lack of up to date tutorials is not helping my confusion.  Any help would be greatly appreciated!</p>
