Return to home UIViewController

Question

I can click 3 times on "< Back" button to return to home UIViewController. I also added image "Home" on navigation. How can I return to first UIViewController, when user clicks on "Home" image? I think I need to add some action

class DoctorsViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let image = UIImage(named: "homeIcon")
        let rightButton = UIBarButtonItem(image: image, style: .done, target: self, action: nil)        
        navigationItem.rightBarButtonItem = rightButton
    }
}

Answer 1

Try this

override func viewDidLoad() {
    super.viewDidLoad()

    let image = UIImage(named: "homeIcon")
    let rightButton = UIBarButtonItem(image: image, style: .done, target: self, action: #selector(self.backBtnClicked))        
    navigationItem.rightBarButtonItem = rightButton
}

func backBtnClicked(_ sender: UIBarButtonItem) {
       _ = self.navigationController?.popToRootViewController(animated: true) // pop to root controller
 }
