title: Swift ios checking if user has enabled notifications always return true
body: <p>I am trying to check if the user has enabled remote notifications for my app but it always return true even if I disable/uninstall my app.</p>
  
  <p>I am checking with this code:</p>
  
  <pre><code>if UIApplication.shared.isRegisteredForRemoteNotifications == false {
      OneSignal.registerForPushNotifications()
      print("Notifications is off")
  } else {
     print("Notifications is on")
  }
  </code></pre>
  
  <p>But this will always run: <code>print("Notifications is on")</code></p>
  
  <p>So how can I check if user has enabled notification for my app?</p>
