title: EKCalendar showing events "Found in Natural Language" which are not in Apple Calendar
body: <p>I am currently reading all calendar events with a function similar to what is described here: <a href="https://www.andrewcbancroft.com/2016/04/28/listing-calendar-events-with-event-kit-and-swift/" rel="nofollow noreferrer">https://www.andrewcbancroft.com/2016/04/28/listing-calendar-events-with-event-kit-and-swift/</a></p>
  
  <p>i.e.</p>
  
  <pre><code>        // Use an event store instance to create and properly configure an NSPredicate
          let eventsPredicate = eventStore.predicateForEventsWithStartDate(startDate, endDate: endDate, calendars: [calendar])
  
          // Use the configured NSPredicate to find and return events in the store that match
          self.events = eventStore.eventsMatchingPredicate(eventsPredicate).sort(){
              (e1: EKEvent, e2: EKEvent) -&gt; Bool in
              return e1.startDate.compare(e2.startDate) == NSComparisonResult.OrderedAscending
          }
  </code></pre>
  
  <p>Now on my iPhone X running iOS 12.1.1 this gives me the various events of a calendar called 'Found in Natural Language'. I know that those are supposed to be the events, which Siri found in apps like Mail etc. I turned this option on under the iPhone Settings -> Calendar. However, the strange thing is that Apple's iOS calendar doesn't show these events, even though the found by Siri calendar is turned on. Some calendar apps like Fantastical don't show them either, and some other apps, like e.g. Vantage calendar show them.</p>
  
  <p>How can that be?</p>
