ios - 在 xcode 11 上运行应用程序后，iPhone 10 和 11 没有足够的高度

Question

所以我在 xcode 10.2.1 中内置了一个应用程序，然后我稍后在 Xcode 11 上运行该应用程序。该应用程序显示黑屏，因为 View 没有足够的高度(只有 48.0，为什么？？？)。所有设备都工作正常，但运行 iOS 13 的 iPhone 10 和 11 确实存在错误。

注意:未使用 Storyboard，该应用程序是在 Xcode 10.2.1 中构建的，swift 5、iOS 13 iPhone 5 - 8 运行良好

这是 View 的层次结构:https://www.dropbox.com/s/e3mzzpwn8iozhc0/Screen%20Shot%202019-10-08%20at%2012.11.18%20PM.png?dl=0

我尝试使用 SceneDelegate 但没有成功。我也尝试过使用场景来选择退出。

AppDelegate.swift

var window: UIWindow?
private var appCoordinator: AppCoordinator!

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        FirebaseApp.configure()

        window = UIWindow()
        appCoordinator = AppCoordinator(window: window!)
        appCoordinator.start{}

        return true
}

AppCoordinator.swift

class AppCoordinator: BaseCoordinator {
    private let window: UIWindow
    private let dependencies: AppDependency

    init(window: UIWindow) {
        self.window = window
        self.dependencies = AppDependency()
    }

    override func start(completion: @escaping CoordinatorCompletion) {
        showTabBarController()
    }

    /// Always represent tabbar controller when authentication state changed
    func showTabBarController() {
        let tabCoordinator = TabCoordinator(window: window, dependencies: dependencies)
        coordinate(to: tabCoordinator)
    }

}

TabCoordinator.swift

class TabCoordinator: BaseCoordinator {
    typealias Dependencies = HasAPIClient & HasUserManager & HasLanguageManager & HasSpotSocketEngine & HasFuturesSocketEngine

    private let dependencies: Dependencies

    enum SectionTab: Int, Menu {
        //case home

解决办法是这样的。对于那些像我一样被这个问题困扰的人。
