iOS 11 prefersLargeTitles not updating until scroll

Question

I implemented a basic UIViewController with a UITableView that\'s wrapped in a UINavigationController. I set prefersLargeTitles to true:

override fu         


        

Answer 1

General changing the behaviour of the navigationBar should be done in viewWillAppear(_:)

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    self.navigationController?.navigationBar.prefersLargeTitles = true
}

After doing that it worked fine for me.
