How to remove all navigationbar back button title

Question

When I push a UIViewController, it has some title in back button at new UIViewController, if the title has a lot of text, It does not look good in

Answer 1

Works on Swift 5:

        self.navigationItem.backBarButtonItem?.title = ""

Please note it will be effective for the next pushed view controller not the current one on the display, that's why it's very confusing!

Also, check the storyboard and select the navigation item of the previous view controller then type something in the Back Button (Inspector).
