        let settings = UIUserNotificationSettings(forTypes: UIUserNotificationType.Alert, categories: nil)
        UIApplication.sharedApplication().registerUserNotificationSettings(settings)
        UIApplication.sharedApplication().setMinimumBackgroundFetchInterval(UIApplicationBackgroundFetchIntervalMinimum)
        return true;
