Here is a version of the answer in

Swift 5

that you can use it from the storyboard:

// MARK: - Hiding Back Button

extension UINavigationItem {

    /// A Boolean value that determines whether the back button is hidden.
    ///
    /// When set to `true`, the back button is hidden when this navigation item
    /// is the top item. This is true regardless of the value in the
    /// `leftItemsSupplementBackButton` property. When set to `false`, the back button
    /// is shown if it is still present. (It can be replaced by values in either
    /// the `leftBarButtonItem` or `leftBarButtonItems` properties.) The default value is `false`.
    @IBInspectable var hideBackButton: Bool {
        get { hidesBackButton }
        set { hidesBackButton = newValue }
    }
}

Every navigation item of a view controller will have this new property in the top section of attributes inspector
