我正试图将NSPersistentContainer的{{1}}传递给SceneDelegate，但我不断收到此错误：
“致命错误：FocusTabBarController需要一个容器”
不确定我在做什么错。请帮忙吗？
UITabBarController：
SceneDelegate let containerObject = (UIApplication.shared.delegate as! AppDelegate).persistentContainer
let tabBarController = FocusTabBarController()
tabBarController.container = containerObject
// Use a UIHostingController as window root view controller.
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
window.rootViewController = tabBarController
self.window = window
window.makeKeyAndVisible()
}
：
FocusTabBarController
