Change navigation root view programmatically objective c

Question

I want to change the navigation's root view controller programmatically using objective c. I am using a storyboard. I tried to change it in-app delegate but didn't work, there's something new introduced called scene delegate where I believe I can change the root from there, but I found no resources for that matter. Can anyone help?

Use below code:

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    var window: UIWindow?
    
    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    
        if let windowScene = scene as? UIWindowScene {
            let window = UIWindow(windowScene: windowScene)
            window.rootViewController = MyRootViewController()
            self.window = window
            window.makeKeyAndVisible()
        }
     }
