Can I move UIbarButtonItem over hidden buttonItem

Question

Can programmatically move the position of Add UIBarButtonItem to the right of the navigation bar. I already have a button there when the button is hidden, I want to move Add button to its position. I used this code to hide the right cornerBtn:

  if arrayAddress.isEmpty == true{
     navigationItem.rightBarButtonItem?.title = ""

        }

If there is no item in tableview the Edit button will be hidden and the plus button move to the corner. My question how can I move plus button?

Here is an image explaining my question

Do you want two buttons showing, and then you want to hide one of them? Or, do you want only one button showing, and you want to change it to a different button? — DonMag, Jun 15 '20 at 20:12

You want to set the .rightBarButtonItems property. You can change this as needed.

So, for example, we'll start with only the + button showing, and when it is tapped we'll also show the Edit button:

class TestViewController: UIViewController {

    lazy var addButton: UIBarButtonItem = {
        let b = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(self.myAddAction(_:)))
        return b
    }()
    lazy var editButton: UIBarButtonItem = {
        let b = UIBarButtonItem(title: "Edit", style: .plain, target: self, action: #selector(self.myEditAction(_:)))
        return b
    }()

    @objc func myAddAction(_ sender: Any) -> Void {
        print("Add button tapped!")
        // this will add both buttons
        self.navigationItem.rightBarButtonItems = [editButton, addButton]
    }
    @objc func myEditAction(_ sender: Any) -> Void {
        print("Edit button tapped!")
    }
    override func viewDidLoad() {
        super.viewDidLoad()

        // let's start with only the "add" button, 
        //   and show the "edit" button after the add button has been tapped
        self.navigationItem.rightBarButtonItems = [addButton]

    }
}
