title: iOS app submission : missing 64-bit support
body: <p>I sent an app yesterday for review, with no problem. I then realized that I had a very little fix to do (changing the max zoom level of a map from 19 to 18, nothing else), so I removed the binary from iTunes Connect, and tried to resubmit.</p>
  
  <p>Now I'm having this warning :</p>
  
  <p><img src="https://i.stack.imgur.com/TXpQT.png" alt="warning_xcode"></p>
  
  <p>I don't understand why, as my architectures are :</p>
  
  <ul>
  <li>architectures : armv7</li>
  <li>valid architectures : armv6, armv7, armv7s, arm64</li>
  </ul>
  
  <p>The app runs fine in the simulator. If I try to use the standard architectures (armv7, arm64) as recommended in the warning, then the app won't build and I get :</p>
  
  <ul>
  <li>Undefined symbols for architecture x86_64</li>
  <li>ld: symbol(s) not found for architecture x86_64</li>
  </ul>
  
  <p>I'm using the lib route-me, and I set the same architecture settings.</p>
