在XCode 6中创建一个新项目不允许禁用Storyboard。您只能选择Swift或Objective-C，而不能使用Core Data。

我尝试删除情节提要，并从项目中删除主情节提要，然后从didFinishLaunching手动设置窗口

在AppDelegate中，我有以下内容：

class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow
var testNavigationController: UINavigationController

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {

        testNavigationController = UINavigationController()
        var testViewController: UIViewController = UIViewController()
        self.testNavigationController.pushViewController(testViewController, animated: false)

        self.window = UIWindow(frame: UIScreen.mainScreen().bounds)

        self.window.rootViewController = testNavigationController

        self.window.backgroundColor = UIColor.whiteColor()

        self.window.makeKeyAndVisible()

        return true
    }
}

但是，XCode给我一个错误：

类“ AppDelegate”没有初始化程序

有人成功吗？
