应用程序在加载时崩溃，根本不调用`didFinishLaunchingWithOptions`

我在现有项目中面临一个奇怪的问题。

从早上开始，我正面临着一场火警事故。

工作正常，没有任何问题，但是从早上开始，我就面临这个问题。

崩溃：

***由于未捕获的异常'NSInternalInconsistencyException'而终止应用程序，原因：'默认FIRApp 必须先配置实例，然后才能设置默认FIRAuthinstance 初始化。确保这一点的一种方法是致电[FIRApp configure]; （在Swift中为FirebaseApp.configure()） application:didFinishLaunchingWithOptions: （在Swift中为application(_:didFinishLaunchingWithOptions:)）。

它清楚地表明，我需要在我的应用程序委托中实现FirebaseApp.configure()，并且自最近6个月以来就已经存在。

AppDelegate代码： 

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        FirebaseApp.configure()
        Messaging.messaging().delegate = self as? MessagingDelegate
        self.getRegisterForRemoteNotifications(application)
        return true
    }

你们可以看到在didFinishLaunchingWithOptions中已调用的Firebase配置在应用启动时仍然面临崩溃问题。

我发现我的appdelegate didFinishLaunchingWithOptions方法没有调用，并且崩溃了我的应用程序。

编辑：

Viewcontroller代码：

var authUI: FUIAuth!

override func viewDidLoad() {
        super.viewDidLoad()
        authUI = FUIAuth.defaultAuthUI()
        authUI?.delegate = self

        if authUI.auth?.currentUser != nil {
            self.checkAdminUser()
            self.getFavPlace()
        }

}

非常感谢任何帮助或指导！

答案 0 :(得分：1)

最后，我发现了我的应用崩溃的原因，而没有调用appDidFinshLaunching()。

这是由于TabViewController之一试图从应用程序委托调用FirebaseApp.configure()之前获取当前用户详细信息。

其直接定义如下。

let user = FIRAuth().auth.currentUser

由于此，它崩溃了。

我将其放在viewDidLoad()方法下，现在该应用程序可以正常运行而不会崩溃。

感谢大家的快速答复，并为我提供指导。

希望此信息对其他人有帮助！
