EKEventstore and unique calendar identifier

Question

I have a question about the EKCalendar calendarIdentifier property. Is this identifier unique at the global level or at the level of each source? For instance. can I safely store the CalendarIdentifier in my application to smoothly identify the calendar for all the calendars in the event store (no matter which EKSource they are in), or do I also need to save the EKSource identifier associated with the calendar?

I have a calendar selection function in my application, and I want to safely store and load the correct calendar (in the correct account) when the application restarts.

Thanks in advance.

From my personal experience and from the description of the property in the link, the EKCalendar class is local to EKEventStore . EKCalendar has the EKSource property as its property at the same level as the calendarIdentifier line.
