Swift version: 5.6
UIBarButtonItems contain either an icon or some text, but they can do so much more – in fact, you can embed any kind of
UIView subclass inside a bar button item, then put that button into a navigation bar or toolbar as you normally would.
For example, you can create a
UIProgressView and place it into a bar button like this:
var progressView = UIProgressView(progressViewStyle: .default) progressView.sizeToFit() let progressButton = UIBarButtonItem(customView: progressView)
