Remove the back button text

Question

Currently trying to remove the title of the previous VC on the back button. Following apple's documentation I have used:

let backBarButtton = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)
navigationItem.backBarButtonItem = backBarButtton

However the back button title does not disappear! The console says it's empty (""), but it's clearly still displayed to the user.

I do not want to use hacks such as setting the previous title of previous VC to "" however currently nothing else seems to be working. Any advice?

Try this function as extension of UINavigationController :

func setBackButtonTitle(_ title: String) {
    if self.navigationBar.topItem != nil {
        let leftBarButtonItem: UIBarButtonItem = UIBarButtonItem(title: title, style: UIBarButtonItem.Style.plain, target: self, action: #selector(self.backButtonAction))
        self.navigationBar.topItem?.backBarButtonItem = leftBarButtonItem
    } else {
        if self.navigationBar.backItem != nil {
            self.navigationBar.backItem?.title = title
        }
    }
}
