title: Shader performance data maybe unavailable due to deployment target older than device version
body: <p>In a nutshell, I just want to know if I should be concerned about this issue:</p>
  
  <p><strong>runtime: GPU Frame Capture</strong>: </p>
  
  <blockquote>
    <p>Shader performance data maybe unavailable due to deployment target
    older than device version</p>
  </blockquote>
  
  <p>The device I am using is running iOS 12.0, and when I had the app set to target iOS 12, this issue was not appearing.</p>
  
  <p>However, after I changed the app's target to 11.4, this appeared.</p>
  
  <p>Based on my reading of it, and the performance of my app following the change, I do not think this is of any real concern and just exists to alert me that there <em>could</em> be problems obtaining shader performance data.</p>
  
  <p>Short of testing against an 11.4 device, is there anything I can or even should, do to remove it?</p>
