Unable to access kABPersonNoteProperty

I have the following code which copies data from the iPhone's contacts into an NSMutableDictionary. I'm using optional binding as discussed in this answer.

The firstName and lastName fields copy properly (as well as phone and email fields not shown here), but I have never been able to access the kABPersonNoteProperty, nor have I seen the println statement in the log. I've tried to copy the note as both String and NSString without success. Any ideas what could be causing this problem?

var contactInfoDict:NSMutableDictionary!

func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController!, didSelectPerson person: ABRecord!) {

    self.contactInfoDict = ["firstName":"", "lastName":"", "notes":""]

    if let firstName:String = ABRecordCopyValue(person, kABPersonFirstNameProperty)?.takeRetainedValue() as? String {
        contactInfoDict.setObject(firstName, forKey: "firstName")
        println(firstName)
    }

    if let lastName:String = ABRecordCopyValue(person, kABPersonLastNameProperty)?.takeRetainedValue() as? String {
        contactInfoDict.setObject(lastName, forKey: "lastName")
        println(lastName)
    }

    if let notes:String = ABRecordCopyValue(person, kABPersonNoteProperty)?.takeRetainedValue() as? String {
        contactInfoDict.setObject(notes, forKey: "notes")
        println("Note: \(notes)")
    }

}

Edit Here is the full class:
