title: EventKit: Deleted calendar reappears
body: <p>I use EventKit in iOS to interact with Calendar.app. In one case, I need to delete a calendar from my app. So I use EventStore.removeCalendar(_:Commit:) function with the commit set to true. The calendar I am trying to delete is an iCloud calendar.</p>
  
  <p>However, I found that after the calendar was deleted, it reappeared back itself. I am positive that it is not my mistake to add the calendar back as I have only one function regarding to creating calendars in my app and it is not called in between the deletion and reappearing.</p>
  
  <p>I suspect it is iCloud who automatically adds it back. I tried to enter fly mode before deletion and the deleted calendar never reappears itself.</p>
  
  <p>Has anyone experienced similar issue? If so, how can I tell iCloud that I want to delete the calendar so don't add it back.</p>
  
  <p>Thanks.</p>
