This is pretty simple to do. But first a little of theory. The backBarButonItem does not affect the current ViewController, it affect the next in the stack of the UINavigationController. I will give you an example. If you have the ViewController A and the ViewController B, then to accomplish your task, you set the backBarButtonItem in A with a blank space in the title. Then when you go A -> B you will see only the arrow in the top left corner.

Exist two way to solve this issue, one in the storyboard and the other is in code.

For the storyboard you need to set like in the next picture the Back Button title with an single space like you can see

The second way is in code, but for this you need an extra code get the dismiss appropriately

First put this code anywhere in your project

extension UIViewController {
    @IBAction func unwind(_ sender: UIStoryboardSegue)
    {

    }
}

With that, then in A ViewController you can do then this:

class ViewControllerA: UIViewController {


    override func viewDidLoad() {
        super.viewDidLoad()

        self.navigationItem.backBarButtonItem = UIBarButtonItem(title: " ", style: .plain, target: self, action: #selector(unwind(_:)))
    }


}

Good coding. Best regards

Okay but I am navigating one storyboard view controller to another view controller.i have set the first way you said but its not working. My storyboard have only one view controller and navigation controller — Arigarasuthan, May 26 '20 at 03:28

Add the below code in your viewDidLoad method

self.navigationController?.navigationBar.topItem?.title = ""

Note : This will remove back button title of current viewController and also it will clear the title of previous ViewController (where the back button is going to), so you have to set the title in viewWillAppear of previous ViewController if you want.
