ios – Google Auth SWIFTUI: Cannot convert value of type ‘GIDConfiguration’ to expected argument type ‘UIViewController’

I am having issues implementing the google sign in process in my swiftUI file. I believe i’ve imported the correct pods and have been at this for hours trying to get this to work, but I keep getting these similar errors on line 142:

1: Cannot convert value of type ‘GIDConfiguration’ to expected argument type ‘UIViewController’
2: Cannot find ‘getRootViewController’ in scope
3: Extra trailing closure passed in call
4: Unable to infer type of a closure parameter ‘error’ in the current context
5: Unable to infer type of a closure parameter ‘user’ in the current context

I’ve been trying to troubleshoot this in various different ways. Not sure what the problem is, pods, SDK, or something with my delegate. Thanks for the help. For some reason I don’t see an Info.plist file on my left toolbar of this new project. (Photo attached below) I tried to create one and target it, but now none of my schemes are building :(( Any help would be greatly appreciated on what is going wrong here!

No Info.plist

Here is my swiftUI code:

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))
    }
}

struct SignUp: View {
    @State private var name: String = ""
    @State private var email: String = ""
    @State private var password: String = ""
    @State private var confirmPassword: String = ""
    
    private var isFormValid: Bool {
        !name.isEmpty && !email.isEmpty && !password.isEmpty && !confirmPassword.isEmpty
    }
    
    private var confirmPasswordFieldColor: Color {
        if confirmPassword.isEmpty {
            return Color.gray
        } else {
            return password == confirmPassword ? Color.green : Color.red
        }
    }
    
    private var passwordFieldColor: Color {
        if !confirmPassword.isEmpty {
            return password == confirmPassword ? Color.green : Color.gray
