title: How to display Xcode code coverage when it's not displaying?
body: <p>I have been trying to get the code coverage for my project using <strong>Xcode 9</strong>. All test cases run successfully but did not generate the code coverage report under the Code coverage tab.</p>
  <p>I tried the following things:</p>
  <ol>
  <li><p>Enable the Gather code coverage in the scheme.</p>
  </li>
  <li><p>Enable Code Coverage Support for my target.</p>
  </li>
  <li><p>Enable the Showcase bundle option.</p>
  <p>Is there an extra setting require to check the code coverage report ? or should I miss something? Thanks in advance.</p>
  </li>
  </ol>
