title: Breakpoints not hit in Xcode (9.3)
body: <p>None of my breakpoints are being hit.</p>
  
  <p>I've tried the following:</p>
  
  <ul>
  <li>Deleted Derived Data directory</li>
  <li>Cleaned build folder</li>
  <li>Deleted the xcuserdata directory</li>
  <li>Made sure build configuration is <code>Debug</code> and <code>Debug executable</code> is
  ticked</li>
  <li>Made sure   <code>Generate debug symbols</code> is set to <code>Yes</code></li>
  <li>Changed <code>Optimization level</code> to <code>No optimization</code></li>
  </ul>
  
  <p>The breakpoints are still not being hit.</p>
