Answer 1

Just create extension of UIViewController with override function awakeFromNib() and make UIBarButtonItem with an empty title and give to navigation backBarButtonItem.

extension UIViewController {

  open override func awakeFromNib() {
    let backBarBtnItem = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)
    navigationItem.backBarButtonItem = backBarBtnItem
  }

}
