title: xcode MainWindow.xib vs ViewController.xib, trying to delete label from viewController.xib?
body: <p>I'm trying to understand the relationship between the ViewController xib and the MainWindows.xib?</p>
  
  <p>I clicked the mainwindow xib from the project navigator a window pops up that I can draw on and then I click the viewcontroller icon and another window pops up besides. I dragged a label onto the viewcontroller.xib and now I cant delete it.</p>
  
  <p>I'm trying to understand the relationship between the two</p>
  
  <p>Sorry for confusing question, just trying to find my way...</p>
  
  <p>Thanks</p>
