title: Localized storyboard is ignored (?)
body: <p>I created a Swedish localization of my storyboard, but it doesn't get loaded for iOS devices with the language set to Swedish - it's always the English version.</p>
  
  <p>I have <code>Localizable.strings</code> in <code>sv.lproj</code>, and those do work when using the <code>NSLocalizedString</code> macro.</p>
  
  <p>Are there some additional steps required? All I did was click the plus sign under the "Localization" section.</p>
