显然没有配置Firebase [英] Firebase not configured when it clearly is

问题描述

我不知道为什么这不起作用，我的Firebase已配置好.这是我的AppDelegate.swift文件的截图.这是我的控制台日志:

I don't know why this isn't working my Firebase is configured. Here is a Screenshot of my AppDelegate.swift file. Here is my console log:

我整个下午都在努力使它工作.请帮忙.

I have tried all afternoon to get this working. Please help.

推荐答案

在您的堆栈跟踪中，我得到的印象是您可能太早访问了 Firebase.Auth 类-也许在<您的VC的code> initWithCoder ?还是作为VC属性的初始值?—可以在 AppDelegate 之前运行(并初始化Firebase).

Looking in your stack trace, I get the impression you might be accessing the Firebase.Auth class too soon — maybe in the initWithCoder of your VC? Or as a VC property initial value? — which could be before your AppDelegate runs (and initializes Firebase).

这样，请尝试将您的 Auth.auth()调用移至 viewDidLoad 方法，以查看它是否有所不同.

As such, try moving your Auth.auth() call to the viewDidLoad method instead to see if it makes a difference at all.
