Hello,

I'm playing with AddressBook framework but I can't figure how access the predefined constants.

For example, in my ViewControler I do like below but XCode can't find kABFirstNamePropery. I already added framework 'AddressBook' in my rb_main.rb:

  def awakeFromNib
    notificationCenter = NSNotificationCenter.defaultCenter
    notificationCenter.addObserver(self, 
                                   selector: "recordChanged:",
                                   name: ABPeoplePickerNameSelectionDidChangeNotification,
                                   object:peoplePicker)
  end

  

  def recordChanged(notification)
    people = peoplePicker.selectedRecords
    person = people.first
    puts kABFirstNameProperty
  end


Anyone can help me with this issue?

Thanks in advance ;)
