How to Change Back Button Title on Navigation Controller in Swift3

How to set back button text in Swift

The back button belongs to the previous view controller, not the one currently presented on screen.

To modify the back button you should update it before pushing, on the view controller that initiated the segue:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let backItem = UIBarButtonItem()
    backItem.title = "Something Else"
    navigationItem.backBarButtonItem = backItem // This will show in the next view controller being pushed
}

Swift 3, 4 & 5:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    let backItem = UIBarButtonItem()
    backItem.title = "Something Else"
    navigationItem.backBarButtonItem = backItem // This will show in the next view controller being pushed
}

OR

// in your viewDidLoad or viewWillAppear
navigationItem.backBarButtonItem = UIBarButtonItem(
    title: "Something Else", style: .plain, target: nil, action: nil)

How do I change the title of the back button on a Navigation Bar

This should be placed in the method that calls the ViewController titled "NewTitle".
Right before the push or popViewController statement.

UIBarButtonItem *newBackButton = 
        [[UIBarButtonItem alloc] initWithTitle:@"NewTitle" 
                                         style:UIBarButtonItemStyleBordered 
                                        target:nil 
                                        action:nil];
[[self navigationItem] setBackBarButtonItem:newBackButton];
[newBackButton release];

Edit:

Once you create the project, you'll see the following in your storyboard:

I changed it to following:

Which gave me the following output:

And following is my code for viewDidLoad() in DetailViewController:

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationController?.navigationBar.tintColor = UIColor.red
    // Do any additional setup after loading the view, typically from a nib.
    configureView()
}

Hope this makes it clear enough now.
