How to remove border in navigationBar in swift?

To remove the border from a navigation bar in swift, we just need to add a few lines of code. Let’s see how the navigation bar looks when we run it without changing anything.

In your viewDidLoad add the following code −

self.navigationController?.navigationBar.shadowImage = UIImage()

When we run the above code, we get the following result −

Now, we’ll also hide the background image just like shadow image, and it will look like the navigation bar has disappeared.
