Change Navigationbar Color swift

Question

Here this code works and the color of the navigationbar changed to blue

override func viewDidLoad() {
    super.viewDidLoad()
    navigationItem.title = "Countries"
    navigationController?.navigationBar.barTintColor = UIColor.blue
    tabBarController?.tabBar.tintColor = UIColor.white
    view.backgroundColor = .white
}

BUT WHEN adding navigationController?.navigationBar.prefersLargeTitles = true

color does not change

override func viewDidLoad() {
    super.viewDidLoad()
    navigationItem.title = "Countries"
    navigationController?.navigationBar.prefersLargeTitles = true
    navigationController?.navigationBar.barTintColor = UIColor.blu
    tabBarController?.tabBar.tintColor = UIColor.white
    view.backgroundColor = .white
}

Answer 1

Here you can use [navigationBar.backgroundColor] instead off [navigationBar. barTintColor]

    navigationItem.title = "Countries"
    
    navigationController?.navigationBar.prefersLargeTitles = true
    
    navigationController?.navigationBar.backgroundColor = UIColor.blue
    
    tabBarController?.tabBar.tintColor = UIColor.white
    
    view.backgroundColor = .white
