How to achieve the auto-shrink SwiftUI Navigation Title with UIKit? - swift

Question

I am trying to achieve the auto-shrink large nav title like the Navigation Title in SwiftUI, but no matter what my nav title always stay shrinked and never appear in large title mode. How do i fix this? (code below)
func setup() {
table.translatesAutoresizingMaskIntoConstraints = false
table.dataSource = self
table.delegate = self
table.register(UITableViewCell.self, forCellReuseIdentifier: "mycell")
table.separatorColor = .white
table.backgroundColor = .black
let appearance = UINavigationBarAppearance()
appearance.titleTextAttributes = [.foregroundColor: UIColor.black]
appearance.largeTitleTextAttributes = [.foregroundColor: UIColor.black]
appearance.configureWithOpaqueBackground()
navigationItem.title = "Todo List"
navigationItem.scrollEdgeAppearance = appearance
navigationItem.standardAppearance = appearance
view.addSubview(table)
}

As well as providing a configuration for large titles, you need to instruct your navigationController to use large titles
navigationController.navigationBar.prefersLargeTitles = true
The default configuration for a view controller should be to automatically use large titles if that is the preferred choice. However you can set it explicitly per view controller:
navigationItem.largeTitleDisplayMode = .always // or .automatic or .never
If the nav controller has prefersLargeTitle = false then large titles will never be displayed whatever the largeTitleDisplayMode setting.
