NavigationBar background color not working in swift5-CodePudding

I am using NavigationBar in swift5. NavigationBar background color shows black color.. here is my image

Here is my code:

    class ViewController: UIViewController {
        override func viewDidLoad() {
            super.viewDidLoad()
            
            self.navigationController?.navigationBar.tintColor = UIColor.red
            self.navigationController?.navigationBar.barTintColor = UIColor.green
            self.navigationController?.navigationBar.barTintColor = .red
            self.navigationItem.title = "ABC title"
            self.navigationController!.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]
            self.navigationController?.navigationBar.isTranslucent = false
        }
    }

What is the problem of my code? Please help me

CodePudding user response：

This is why in iOS 15 NavigationBars use the scrollEdgeAppearance, if you want to use old appearance you have to declare it like this :

override func viewDidLoad() {
        super.viewDidLoad()
        let appearance = UINavigationBarAppearance()
        appearance.configureWithOpaqueBackground()
        appearance.backgroundColor = .red
        appearance.titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]
        self.navigationController?.navigationBar.standardAppearance = appearance;
        self.navigationController?.navigationBar.scrollEdgeAppearance = self.navigationController?.navigationBar.standardAppearance
        
        self.navigationItem.title = "ABC title"
    }

That's the result :
