title: Error when uploading iOS app after updating to Xcode 7.0.1
body: <p>I get these errors when uploading an iOS app in Xcode 7.0.1. No errors when using Xcode 7.0. </p>
  
  <p>ERROR ITMS-90030: "Nib file 'MainWindow~ipad.nib' was not found. Please ensure the specified file is included in the bundle with any required device modifiers appended to the filename."</p>
  
  <p>ERROR ITMS-90030: "Nib file 'MainWindow~iphone.nib' was not found. Please ensure the specified file is included in the bundle with any required device modifiers appended to the filename."</p>
  
  <p>The app contains two xib files, but not any nib-files:
  MainWindow.xib
  MainWindow~ipad.xib</p>
  
  <p>In Targets / General / Deployment Info: 
  iPhone: Main Interface: MainWindow
  iPad:   Main interface: MainWindow~ipad</p>
  
  <p>In the plist-file:
  Main nib file base name:  MainWindow
  Main nib file base name (iPad) MainWindow~ipad</p>
  
  <p>Is there an easy way to convert a xib-file to a nib-file?</p>
  
  <p>Any idea how to solve the problem?</p>
