所以我有一个内置在 xcode 10.2.1 中的应用程序，然后我后来在 Xcode 11 上运行该应用程序。该应用程序显示黑屏，因为视图没有足够的高度(只有 48.0，为什么???(。所有设备都运行良好，但在iOS 10上运行的iPhone 11和13确实存在错误。
注意：没有使用故事板，该应用程序是在Xcode 10.2.1，swift 5，iOS 13 iPhone 5 - 8中构建
的，工作正常下面是视图的层次结构：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，但没有奏效。我还尝试使用场景选择退出。
应用委托.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
}
应用协调员.swift
class AppCoordinator: BaseCoordinator {
private let window: UIWindow

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)

}
解决方案是这样的。对于那些像我一样陷入这个问题的人。
