Before changes in UIKit iOS 13 how I can set rootViewController at SceneDelegate?

FYI since SwiftUI doesn't use storyboards if you just make a new SwiftUI project it will give you the code; all you need to do is replace the UIHostingViewController with your desired root VC like this:

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()
    }
  }
