EKReminder error when creating on OS X: No calendar has been set

Question

I have a snippet of code that is attempting to save a generic reminder, using the EventKit framework in OS X 10.8 and newer. Here is my code snippet:

NSLog(@"Creating reminder.");
EKEventStore *eventStore = [[EKEventStore alloc] initWithAccessToEntityTypes:EKEntityMaskReminder];
NSLog(@"Auth status: %lu", [EKEventStore authorizationStatusForEntityType:EKEntityTypeReminder]);

[eventStore requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) {
    NSLog(@"Granted: %d Error: %@", granted, error);
    if (granted) {
        EKReminder *reminder = [EKReminder reminderWithEventStore:eventStore];
        reminder.title = @"My Reminder";
        EKCalendar *reminderCalendar = [EKCalendar calendarForEntityType:EKEntityTypeReminder eventStore:eventStore];
        NSLog(@"Using EKCalendar: %@", reminderCalendar);
        reminder.calendar = reminderCalendar;

        NSError *commitError = nil;
        if (![eventStore saveReminder:reminder commit:YES error:&commitError] || commitError) {
            NSLog(@"An error occurred committing the reminder: %@", commitError);
        } else {
            NSLog(@"Reminder created successfully.");
        }
    }
}];

And here is the output I see:

2014-01-08 19:56:21.182 MyApp[6073:303] Creating reminder.

However, despite the error message, the EKCalendar has been successfully created/accessed, and set on the EKReminder object.

The only other similar resources I've found for this error occur when using EventKit on iOS, in which the method for gaining access is slightly different.

According to this Apple doc: https://developer.apple.com/library/ios/documentation/DataManagement/Conceptual/EventKitProgGuide/ReadingAndWritingReminders/ReadingAndWritingReminders.html

You can create reminders using the reminderWithEventStore: class method. The title and calendar properties are required. The calendar for a reminder is the list with which it is grouped.

But I must be doing something wrong. Under my App Sandbox/App Data permissions, I have selected both Calendar and Contacts just to be safe, but the error seems unrelated to permissions.

Instead of using:

EKCalendar *reminderCalendar = [EKCalendar calendarForEntityType:EKEntityTypeReminder eventStore:eventStore];
NSLog(@"Using EKCalendar: %@", reminderCalendar);
reminder.calendar = reminderCalendar;

I was able to create the EKReminder successfully using:

reminder.calendar = [eventStore defaultCalendarForNewReminders];
