"Take Photo" is not showing in CNContact iOS 11

Question

I have a UIButton name as "Add new contact", When I click on this, a new contact screen is opened but when I tap on "Add Photo" then only "Choose Photo" is coming and "Take Photo" is not coming in iOS 11. The code for new contact is -

let con = CNContact()
    let vc = CNContactViewController(forNewContact: con)
    vc.delegate = self
    let navVC = UINavigationController(rootViewController: vc)
    self.present(navVC, animated: true, completion: nil)
