  <pre><code>This iPhone 8 Plus ... is running iOS 11.4.1 (15G77), which may not be supported by this version of Xcode
  </code></pre>
  
  <p>I have macOS 10.12.6 and Xcode 9.1 and Xcode 9.2 but I get the error on both versions.</p>
  
  <p><strong>How can I still run the app on my device, should I downgrade the IOS or there is another way ?</strong></p>
