title: IOS10: badge count not displayed
body: <p>I am using the following code to display a number as badge at my apps icon:</p>
  
  <pre><code>func triggerNotification(iAmountToday: Int) {
    UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert]) { (granted, error) in
      if granted {
        let content = UNMutableNotificationContent()
        content.badge = iAmountToday
        content.categoryIdentifier = "com.psv.localNotification"
        let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 1.0, repeats: false)
        let request = UNNotificationRequest.init(identifier: "AmountTodayUpdate", content: content, trigger: trigger)
  
        let center = UNUserNotificationCenter.currentNotificationCenter()
        center.addNotificationRequest(request, withCompletionHandler: { (error) in
          if (error != nil) {
            print (error)
          }
        })
      }
    }
  }
  </code></pre>
  
  <p>Although no error is thrown, the badge is never shown at the apps icon.</p>
  
  <p>What am I doing wrong?</p>
  
  <p>Cheers</p>
