title: Do remote push notifications require to add UIBackgroundModes in Info.plist?
body: <p>I have integrated remote push notifications, but I am getting this warning:</p>
  
  <blockquote>
    <p><code>didReceiveRemoteNotification:fetchCompletionHandler:]</code>, but you still
    need to add "<code>remote-notification</code>" to the list of your supported
    <code>UIBackgroundMode</code>s in your <code>Info.plist</code>.</p>
  </blockquote>
  
  <p>My Xcode version is 8.3.1. I really want to add this to <code>Info.plist</code>. I have followed some tutorials as well but they didn't mentioned this either. What should I really do?</p>
