BirthdayContactIdentifier BAD_ACCESS

Question

當我從EKEvent訪問屬性BirthdayContactIdentifier時，我總是立即收到BAD_ACCESS錯誤（甚至無法無效檢查）

這是我用來獲取的代碼

import UIKit  
import EventKit  
class ViewController: UIViewController {  

let eventStore : EKEventStore = EKEventStore()  
override func viewDidLoad() {  
    super.viewDidLoad()  

    eventStore.requestAccessToEntityType(.Event) { (granted, error) in  
        if granted == true {  
            let startDate = NSDate()  
            let endDate = startDate.dateByAddingTimeInterval(7.0*86400.0)  

            let events = self.eventStore.eventsMatchingPredicate(self.eventStore.predicateForEventsWithStartDate(startDate, endDate: endDate, calendars: nil))  

            for event in events {  
                if event.calendar.type == .Birthday {  
                    NSLog("\(event.title)")  
                    NSLog("\(event.birthdayContactIdentifier)") // BAD_ACCESS  
                }  
            }  
        }  
     }   
  }  
}

我在這里找到錯誤號22475180。 嘗試BirthdayPersonID。 目前從iOS 9開始不推薦使用，但可能會有所不同
