Setting navigationItem title delay issues

When pushing a controller to the navigation stack i execute:

self.navigationItem.title = "";

As i dont want the next view to show the name of the previous controller on the back button.

When i get back to that controller i do this:

override func viewWillAppear(_ animated: Bool) {
    self.navigationItem.title = "Title Of View";
    ...
}

The title is set appropriately but it lags for about 1 second or so.. I remember using this techinique for quite some time without having a problem in the past. The code that sets the titles isn't within a network call or anything like that..

Any ideas about what might be causing this?

In order to hide the back button title you should set empty UIBarButtonItem instance to the self.navigationItem.backBarButtonItem right after you push the new view controller, like so:

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

This way you don't have to manipulate the title of the view controller.
