title: XCode custom segue class stuck
body: <p>this question might seem a little weird, but I can't wrap my head around why this is happening.</p>
  
  <p>What I did was I renamed a custom segue class, and reflected it in the storyboard under 'custom class', but it still tries to call the old one.</p>
  
  <p>I have cleaned the build folder and searched the project for the old custom class name and it does not find anything in xcode at least. I look inside the storyboard file, it's not there either.</p>
  
  <p>Even if I delete the custom segue all toghether I get:</p>
  
  <pre><code>'Could not find a segue class named 'xxxxxxxxx''
  </code></pre>
  
  <p>The thing is I cannot understand from where it gets 'xxxxxxxxx' above, it is not in the storyboard file or in the code..</p>
  
  <pre><code>[[[self view] viewWithTag:1] resignFirstResponder];
  </code></pre>
  
  <p>When I debug this is where it goes to thread kill showing the error. I have removed all the outlets, events and segues on the textfield. I have no custom segue using 'xxxxxxxxx' as a class anywhere.</p>
  
  <p>Is there any other thing I can do to clean the project more thoroughly? Where to begin?</p>
