title: Xcode 4.5 - CopyPNGFile persists. Need new ideas
body: <p>I'm making an iPad app and it runs on the simulator, but fails when i try building it for the device. </p>
  
  <p>the error is below:</p>
  
  <p><img src="https://i.stack.imgur.com/8XiVt.png" alt="enter image description here"></p>
  
  <p>These are the things i've tried to rectify this issue:</p>
  
  <ul>
  <li>went through every PNG file with Photoshop and saved them again w/o the interlace</li>
  <li>Deleted all the images in my Resources folder and added them again by dragging/dropping the images again</li>
  <li>Deleted ALL PNG images (left the JPGs) and it works...when i add one PNG, Xcode throws a hissy fit.</li>
  <li>Deleted the derivedData in my ~Library/Developer/Xcode</li>
  <li>quit Xcode and tried again</li>
  <li>restarted my computer and tried again.</li>
  </ul>
  
  <p>i tried checking about the paths, but i'm not sure. Any ideas would be great please.</p>
  
  <p><em>Addendum</em>
  i also want to add that Xcode is throwing errors against its own Default@2x.png and Default.png!</p>
