 正直まだ正しい対応なのか確証が持てていないので、もう少し調査する必要があるかもしれません。

+## 追記(2019/10/03)
+Xcode11でiOS13のターゲットのプロジェクトを作成した場合は`SceneDelegate`や`AppDelegate`はそのままで問題ないと思います。
+[参考にさせていただいたサイト](https://tech.yappli.io/entry/scenedelegate)をみたところ
+> 「ライフサイクルイベント」が発生したときは SceneDelegate か AppDelegate のどちらかのメソッドしか呼ばれない
+iOS 13 かつ SceneDelegate が使用されている場合は SceneDelegate が
+それ以外では AppDelegate が
+となっていたので、
+ちょっと自信がありませんが、上記の対応が必要になるのは**Xcode11でiOS12.x以下をターゲットとしたプロジェクトを作成した時**だと思います。
+手元で以下のようなコードで生成したViewControllerをルートにして実行することができたので、
+参考として貼っておきます。
+```Swift
+// CodeViewController
+import UIKit
+final class CodeViewController: UIViewController {
+    // MARK: - UI
+    lazy var titleLabel: UILabel = {
+        let label = UILabel()
+        label.translatesAutoresizingMaskIntoConstraints = false
+        label.font = UIFont.boldSystemFont(ofSize: 18)
+        label.text = "Title"
+        return label
+    }()
+    lazy var descLabel: UILabel = {
+        let label = UILabel()
+        label.translatesAutoresizingMaskIntoConstraints = false
+        label.font = UIFont.systemFont(ofSize: 15)
+        label.textColor = UIColor.lightGray
+        label.text = "Desc"
+        return label
+    }()
+    lazy var button: UIButton = {
+        let button = UIButton()
+        button.translatesAutoresizingMaskIntoConstraints = false
+        button.setTitle("Button", for: .normal)
+        button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 15)
+        button.titleLabel?.textColor = UIColor.white
+        button.backgroundColor = UIColor.blue
+        button.layer.cornerRadius = 4.0
+        return button
+    }()
+    // MARK: - Lifecycle
+    override func viewDidLoad() {
+        super.viewDidLoad()
+        // UI
+        view.backgroundColor = .white
+        view.addSubview(titleLabel)
+        view.addSubview(descLabel)
+        view.addSubview(button)
+        setupLayout()
+    }
+}
+// MARK: - AutoLayout
+extension CodeViewController {
+    func setupLayout() {
+        // titleLabel
+        NSLayoutConstraint.activate([
+            titleLabel.centerXAnchor.constraint(equalTo: view.centerXAnchor, constant: 0),
+            titleLabel.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: 0)
+            ])
+        // descLabel
+        NSLayoutConstraint.activate([
+            descLabel.topAnchor.constraint(equalTo: titleLabel.bottomAnchor, constant: 8),
+            descLabel.centerXAnchor.constraint(equalTo: titleLabel.centerXAnchor, constant: 0)
+            ])
+        // button
+        NSLayoutConstraint.activate([
+            button.topAnchor.constraint(equalTo: descLabel.bottomAnchor, constant: 16),
+            button.centerXAnchor.constraint(equalTo: descLabel.centerXAnchor, constant: 0),
+            button.widthAnchor.constraint(equalToConstant: 88),
+            button.heightAnchor.constraint(equalToConstant: 44)
+            ])
+    }
+}
+```
+AppDelegateはプロジェクト生成時のままです。
+```Swift
+// AppDelegate
+import UIKit
+@UIApplicationMain
+class AppDelegate: UIResponder, UIApplicationDelegate {
+    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
+        // Override point for customization after application launch.
+        return true
+    }
+    // MARK: UISceneSession Lifecycle
+    func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
+        // Called when a new scene session is being created.
+        // Use this method to select a configuration to create the new scene with.
+        return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
+    }
+    func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
+        // Called when the user discards a scene session.
+        // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
+        // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
+    }
+}
+```
+SceneDelegateが`window`プロパティを持っているようなので、
+ここでrootViewControllerの設定をしました。
+色々変わっていたので[こちら](https://qiita.com/rc_code/items/795ddadb98dfa09d10e6)を参考にさせていただきました。
+```Swift
+class SceneDelegate: UIResponder, UIWindowSceneDelegate {
+    var window: UIWindow?
+    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
+        // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
+        // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
+        // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
+        guard let _ = (scene as? UIWindowScene) else { return }
+        if let windowScene = scene as? UIWindowScene {
+            let window = UIWindow(windowScene: windowScene)
+            window.rootViewController = CodeViewController(nibName: nil, bundle: nil)
+            self.window = window
+            window.makeKeyAndVisible()
+        }
+    }
+    func sceneDidDisconnect(_ scene: UIScene) {
+        // Called as the scene is being released by the system.
+        // This occurs shortly after the scene enters the background, or when its session is discarded.
+        // Release any resources associated with this scene that can be re-created the next time the scene connects.
+        // The scene may re-connect later, as its session was not neccessarily discarded (see `application:didDiscardSceneSessions` instead).
+    }
+    func sceneDidBecomeActive(_ scene: UIScene) {
+        // Called when the scene has moved from an inactive state to an active state.
+        // Use this method to restart any tasks that were paused (or not yet started) when the scene was inactive.
+    }
+    func sceneWillResignActive(_ scene: UIScene) {
+        // Called when the scene will move from an active state to an inactive state.
+        // This may occur due to temporary interruptions (ex. an incoming phone call).
+    }
+    func sceneWillEnterForeground(_ scene: UIScene) {
+        // Called as the scene transitions from the background to the foreground.
+        // Use this method to undo the changes made on entering the background.
+    }
+    func sceneDidEnterBackground(_ scene: UIScene) {
+        // Called as the scene transitions from the foreground to the background.
+        // Use this method to save data, release shared resources, and store enough scene-specific state information
+        // to restore the scene back to its current state.
+    }
+}
+```
+この状態で`Main`のStoryboardを削除したところ質問者様と同じ
+> Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'Main' in bundle NSBundle
+上記のエラーが出たので、
+Xcodeの`Main Interface`を空にして、
+info.plistの`Scene Configuration`の`Storyboard Name`の項目を削除しました。
+![info.plist](ecbc47ffd58bc39e91cd339f7a0d4aaf.png)
+これで一応エラーなしで起動することができました、
+正直まだ正しい対応なのか確証が持てていないので、もう少し調査する必要があるかもしれません。
+曖昧な回答しかできず申し訳ありません。
