title: See logs before & after app restart
body: <p>I have my iPhone app running on device, I can see logs in xcode. </p>
  
  <p>Then, I what to see logs about what is happening when app restart. </p>
  
  <p>So, I <strong>press home button twice -> swipe up</strong> to stop my app, then launch the app again. But I can't see any log in xcode anymore. </p>
  
  <p>How can I see logs of my app continuously before &amp; after my app restart in xcode?</p>
  
  <p><strong>==== UPDATE ===</strong></p>
  
  <p>I mean app log. OK, I can narrow my question to: How can I see logs again after I restarted my app? (device is connected to my mac book , I saw app logs in xcode before restarting, but can't find a way to see app logs after I restarted my app).</p>
