body: <p>i got a problem with this code</p>
  
  <pre><code>import UIKit
  import EventKit
  
  let eventStore = EKEventStore()
      eventStore.requestAccessToEntityType(EKEntityType.Event, completion: { (success, accessError) -&gt; Void in
          if accessError != nil {
              print("Calendar Access Error: \(accessError)")
              return
          }
          let event = EKEvent(eventStore: eventStore)
  
          event.title = self.detailItem!.title
          event.allDay = true
          event.startDate = self.detailItem!.date
          event.endDate = self.detailItem!.date
          event.calendar = eventStore.defaultCalendarForNewEvents
          var saveToCalendarError: NSError?
          let success: Bool
          do {
              //Swift2: use of unresolved identifier 'EKSpanThisEvent'
              try eventStore.saveEvent(event, span: EKSpanThisEvent)
              success = true
          } catch var error as NSError {
              saveToCalendarError = error
              success = false
          } catch {
              fatalError()
          }
  </code></pre>
