Google 身份验证 SWIFTUI：无法将类型为“GIDConfiguration”的值转换为预期的参数类型“UIViewController”

问：

我在 swiftUI 文件中实现 google 登录过程时遇到问题。我相信我已经导入了正确的 pod，并且已经花了几个小时试图让它工作，但我在第 142 行不断收到这些类似的错误：

1：无法将类型为“GIDConfiguration”的值转换为预期的参数类型“UIViewController” 2：在作用域中找不到“getRootViewController” 3：在调用中传递了额外的尾随闭包 4：无法推断当前上下文中闭包参数“错误”的类型 5：无法推断当前上下文中闭包参数“user”的类型

我一直在尝试以各种不同的方式解决这个问题。不确定问题出在哪里，pods，SDK或我的委托。感谢您的帮助。出于某种原因，我在这个新项目的左侧工具栏上看不到 Info.plist 文件。（下图附上）我试图创建一个并瞄准它，但现在我的计划都没有建立:(（ 对于这里出了什么问题，任何帮助将不胜感激！

没有 Info.plist

这是我的swiftUI代码：

import SwiftUI
import Firebase
import AuthenticationServices
import UIKit
import GoogleSignIn

// Define the CustomTextFieldStyle here
struct CustomTextFieldStyle: TextFieldStyle {
    var borderColor: Color

    func _body(configuration: TextField<Self._Label>) -> some View {
        configuration
            .padding(10)
            .background(RoundedRectangle(cornerRadius: 8).fill(Color.white))
            .overlay(RoundedRectangle(cornerRadius: 8).stroke(borderColor, lineWidth: 1))
    }
}
