title: refreshPreferences HangTracerEnabled / HangTracerDuration messages in iOS 11 + Xcode 9
body: <p>When update to iOS 11, after run app in iPhone, I receive this message in Xcode console:</p>
  
  <pre><code>SibDiet[924:111682] refreshPreferences: HangTracerEnabled: 0
  SibDiet[924:111682] refreshPreferences: HangTracerDuration: 500
  SibDiet[924:111682] refreshPreferences: ActivationLoggingEnabled: 0 ActivationLoggingTaskedOffByDA:0
  </code></pre>
  
  <p>And now I get this message in every simulator and app.</p>
  
  <p>How can I solve this problem?</p>
