    UIBarButtonItem.appearance().setBackButtonTitlePositionAdjustment(UIOffsetMake(0, -60), for:UIBarMetrics.default)

I use above to remove the backButtonTitle prior to iOS 11. But on iOS 11 that is not properly working. Arrow shifts bit downwards. enter image description here How to fix this?

Edit: Other way by erasing Title can solve my problem but my concern is why that old way is not working anymore.

The other way is to set UINavigationControllerDelegate for your navigationController and erase the title in its function.

class NoBackButtonTitleNavigationDelegate: UINavigationControllerDelegate {

    func navigationController(
        _ navigationController: UINavigationController,
        willShow viewController: UIViewController,
        animated: Bool
    ) {
        viewController.navigationItem.backBarButtonItem = UIBarButtonItem(title: " ", style: .plain, target: nil, action: nil)
    }
}

Use this code,

var newBackButton = UIBarButtonItem(image: UIImage(named: "back"), style: .plain, target: self, action: #selector(self.back))
navigationItem?.leftBarButtonItem = newBackButton

Create Navigation controller class as below. Assign this "CustomNavViewController" to UINavigationController in your StoryBoard

class CustomNavViewController: UINavigationController,UINavigationControllerDelegate 
{


override func viewDidLoad() {
    super.viewDidLoad()

    self.delegate = self
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


func navigationController(
    _ navigationController: UINavigationController,
    willShow viewController: UIViewController,
    animated: Bool
    ) {
    viewController.navigationItem.backBarButtonItem = UIBarButtonItem(title: " ", style: .plain, target: nil, action: nil)
}

}

So, no need to do it in every viewControllers. At last remove below line from AppDelegate class if present,

UIBarButtonItem.appearance().setBackButtonTitlePositionAdjustment(UIOffsetMake(0, -60), for:UIBarMetrics.default)

Instead of moving title vertically you can move horizontally. Also in case the title is long you can make its color transparent. Works just fine me:

let barButtonItemAppearance = UIBarButtonItem.appearance()
    barButtonItemAppearance.setTitleTextAttributes([NSAttributedStringKey.foregroundColor: UIColor.clear], for: .normal)
    barButtonItemAppearance.setBackButtonTitlePositionAdjustment(UIOffsetMake(-200, 0), for:UIBarMetrics.default)
