title: iOS 8.0 Beta Unknown UIKit Log
body: <p>Xcode Beta Version 6.0 (6A267n), iOS 8.0 Beta 5 (12A4345d)</p>
  
  <p>I'm getting an unknown log related to uikit library that I've never seen before. </p>
  
  <blockquote>
    <p>17545849:_UIScreenEdgePanRecognizerEdgeSettings.edgeRegionSize=13.000000</p>
  </blockquote>
  
  <p>It looks like <code>UIKit.h</code> associated libraries, but I can't find <code>UIScreenEdgePanRecognizerEdgeSetting</code>s.</p>
  
  <p>What is it?</p>
