Answer 1

I've tried a couple of answers and I can't get them to work in all cases. So this is a workaround to not affect the title of the navigation bar if it's set.

    guard let items = viewController.navigationController?.navigationBar.items else { return }
    for item in items {
        if item.title == nil {
            item.title = ""
        }
    }
