Use the below code

self.navigationItem.setHidesBackButton(true, animated:true);
addNavButtons()

//MARK:- NAVIGATION BUTTONS
func addNavButtons(){

    let btn_back = UIButton(type: .custom)
    btn_back.setImage(UIImage(named: "icon_back"), for: .normal)
    btn_back.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
    btn_back.addTarget(self, action: #selector(goBack), for: .touchUpInside)
    btn_back.imageView?.contentMode = UIViewContentMode.scaleAspectFit
    let menuitem1 = UIBarButtonItem(customView: btn_back)
    self.navigationItem.setLeftBarButtonItems([menuitem1], animated: true)

    let btn_search = UIButton(type: .custom)
    btn_search.setImage(UIImage(named: "searchby_icon"), for: .normal)
    btn_search.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
    btn_search.addTarget(self, action: #selector(SearchButtonClick), for: .touchUpInside)
    btn_search.imageView?.contentMode = UIViewContentMode.scaleAspectFit
    let menuitem2 = UIBarButtonItem(customView: btn_search)

    self.navigationItem.setRightBarButtonItems([menuitem2], animated: true)
}

@objc func goBack(sender:UIButton!) {
     _ = navigationController?.popViewController(animated: true)
}

@objc func SearchButtonClick(sender:UIButton!) {

}

First, Create BaseViewController in your project and set backButton hide code and add custom back button code in viewDidLoad.

After that, all the controller of your project should inherit from BaseViewController so new back button enables for all controller.

BaseViewContorller

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationItem.hidesBackButton = true 
    self.setBackButton()// Set Custom back button
}

Set Custom BackButton Code

//Add Custom Back Button
fileprivate func setBackButton() {
    let button   = UIButton(type: UIButton.ButtonType.custom) as UIButton
    button.frame = CGRect(x: 0, y: 0, width: 44, height: 44)
    button.contentHorizontalAlignment = .fill
    button.contentVerticalAlignment = .fill
    button.imageView?.contentMode = .center
    button.contentEdgeInsets = UIEdgeInsets(top: 0, left: -10, bottom: 0, right: 0)

    button.setImage(UIImage(named: "backButton.png"), for: .normal)
    button.addTarget(self, action: #selector(btnBackActionHandler(_:)), for:.touchUpInside)
    self.navigationItem.leftBarButtonItem = UIBarButtonItem(customView: button)

}


@objc func btnBackActionHandler(_ sender : AnyObject) {
    self.navigationController?.popViewController(animated: true)
}
