无法更改 Main.storyboard 在 iOS 13 [Xcode 11 GM seed 2] 上的名称

Question

在 iOS 13 模拟器和 Xcode 11 GM 种子 2 上，应用程序在 Main.storyboard 的名称更改后崩溃（Info.plist 也更改）。将选项 Main Interface 设置为空会导致同样的问题。 iOS 13 系统总是试图找到 Main.storyboard，但失败并显示崩溃消息：

*** reason: 'Could not find a storyboard named 'Main' in bundle

在 iOS 12 和更早版本上一切正常。 它看起来像是 iOS 13 中的错误。

有没有人遇到同样的问题？有什么解决办法吗？

Answer 1

把Main.storyboard的名字改成Info.plist，再把Main storyboard file base name改成Main.storyboard。当然，你也可以从General-Deployment info改成-Main Interface.

Answer 2

Swift 5 与 iOS 13

One more changes require in info.plist file under Application Scene Manifest group.

在应用程序场景清单中也更改名称。

补充：
如果要在 iOS13 上创建没有故事板 的根 window ，则需要从中删除 Main storyboard file base name 和 Storyboard Name 项目Info.plist，然后在 SceneDelegate:

中以编程方式创建 window

class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        if #available(iOS 13.0, *) {
            //Do nothing here
        } else {
            window = UIWindow(frame: UIScreen.main.bounds)
            window?.makeKeyAndVisible()
        }

        return true
    }
}

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    var window: UIWindow?

    @available(iOS 13.0, *)
    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 windowScene = (scene as? UIWindowScene) else { return }
        window = UIWindow(windowScene: windowScene)
        // continue to create view controllers for window
    }

    //......
}
