title: Xcode 4.5 Automatically changing .xib files
body: <p>Since I upgraded to Xcode 4.5 I've found that it's automatically removing a section of each xib file I visit.  Here is the section:    </p>
  
  <pre><code>&lt;object class="NSMutableDictionary" key="IBDocument.PluginDeclaredDependencyDefaults"&gt;
          &lt;string key="NS.key.0"&gt;com.apple.InterfaceBuilder.CocoaTouchPlugin.iPhoneOS&lt;/string&gt;
          &lt;real value="1536" key="NS.object.0"/&gt;
  &lt;/object&gt;
  </code></pre>
  
  <p>I can almost live with this, but when I go visit the file again I find there are even more 'auto' changes.  They are more varied and harder to characterize so I won't include examples unless I really need to.  </p>
  
  <p>I don't understand what's going on here.  I'm looking for one of two answers:</p>
  
  <ol>
  <li>Is there some way to disable this?</li>
  <li>Why is this happening and is there some way to force Xcode to apply these changes to all xib files so I can be done with this?</li>
  </ol>
  
  <p>I would feel a lot better if I just understood what the heck is going on and why.</p>
