Avoid showing "back" for back button when navigation title is long in Swift

There is a navigation in my project which I want to config it's navigation back item.
First case: When the UINavigation title is long the title of back button is set to "back"

replacing back button title to "back"

Second case: when it is longer this "back" is not shown.

delete back button title and just show back icon

But I want to show just back icon in the first case too.

Here's Objective-C

[self.navigationItem setHidesBackButton:YES];

Here's Swift

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

Edit: if you wish to remove the text only, then here's Objective-C

[self.navigationItem.title = @""];

Here's Swift

self.navigationItem.title = ""

Then you'll need to refresh the nav bar

self.navigationController?.navigationBar.setNeedsLayout()
self.navigationController?.navigationBar.setNeedsDisplay()

Add this in viewDidLoad of ViewController which is pushing next ViewController (View Controller Linguini Arabbiatta)

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

It will show just a back icon in all the View Controllers which are pushed from that View Controller.

Try this code

if let title = self.navigationController?.navigationBar.backItem?.title {

    if title.characters.count > 5 {
        self.navigationController?.navigationBar.backItem?.title = "Anything Else"
    }
}
