title: xcode error: ...this class is not key value coding-compliant for the key ibShadowedLargeTitleTextAttributes
body: <p>I keep getting this error. The app worked before I used a color set. </p>
  
  <p>The error says something about <code>ibShadowedLargeTitleTextAttributes</code>. I dont have any color set for the large title shadow, I am using the default (clear). I restarted Xcode, used a color for the shadow, removed it again. The error keeps showing up when I want to run it, but the built succeeds.</p>
  
  <p>The full error message:</p>
  
  <pre><code>Terminating app due to uncaught exception 'NSUnknownKeyException', 
  reason: '[&lt;UINavigationBar 0x10650fd10&gt; valueForUndefinedKey:]: 
  this class is not key value coding-compliant for the 
  key ibShadowedLargeTitleTextAttributes.'
  </code></pre>
  
  <p>Edit: The App is working when I choose another color for the title text (one that is not part of the color set). This is very strange since I use the exact same color for other text in the app. It is a color I made in a color set. I made a new color in the color set, it is also not working. I have to use a standard color or choose one from the standard color window.</p>
