问题

以下是您的代码的翻译部分：

我最近一直在构建一个应用程序，该应用程序通过Google Firebase使用Google Sign-In。我在修复此错误时遇到了麻烦。

这是我的代码：

import SwiftUI
import Firebase
import GoogleSignIn
import FirebaseAuth

struct LoginView: View {
    @State private var email = ""
    @State private var password = ""
    @State private var isShowingRegistrationView = false
    @EnvironmentObject var contentVM: ContentViewModel
    var body: some View {
        ZStack{
            Image("background1")
                .resizable()
                .ignoresSafeArea()
            VStack{
                VStack{
                    Text("登录")
                        .font(.system(size: 42, weight: .bold, design: .rounded))
                        .foregroundColor(.white)
                    Text("继续")
                        .font(.title3)
                        .foregroundColor(.white.opacity(0.7))
                }
                .padding(.vertical, 60)
                VStack{
                    TextField("输入电子邮件", text: $email)
                        .textInputAutocapitalization(.never)
                        .disableAutocorrection(true)
                        .modifier(CustomTextField())
                    SecureField("输入密码", text: $password)
                        .textInputAutocapitalization(.never)
                        .disableAutocorrection(true)
                        .modifier(CustomTextField())
                }
                .padding(.horizontal)
                .padding(.top, 60)
                Spacer()
                VStack(spacing: 20){
                    Button{
                        Task{
                            await contentVM.signIn(withEmail: email, password: password)
                        }
                    } label: {
                        Text("登录")

                        .font(.subheadline)
                        .foregroundColor(.white)
                    Button {
                        isShowingRegistrationView = true
                    } label: {
                        Text("注册")
                            .font(.subheadline.bold())

                    .underline()
                GoogleSignInBtn {
                    guard let clientID = FirebaseApp.app()?.options.clientID else { return }

                    let config = GIDConfiguration(clientID: clientID)

                    //MARK: 错误出现在这里
                    GIDSignIn.sharedInstance.signIn(with: config, presenting: getRootViewController()) {  user, error in

                        if let error = error {
                            //...
                            return
                        }

                        guard
                            let authentication = user?.authentication,
                            let idToken = authentication.idToken
                        else {
                            return
                        }

                        let credential = GoogleAuthProvider.credential(withIDToken: idToken,
                                                                       accessToken: authentication.accessToken)

The issue is the code that is generating the error .signIn(with: config, presenting: ... is no longer the correct syntax. Looks like some updates were made on the google side of things.

Try replacing the block of code within the GoogleSiginBtn with the following:

guard let clientID = FirebaseApp.app()?.options.clientID else { return }

let config = GIDConfiguration(clientID: clientID)

GIDSignIn.sharedInstance.configuration = config

GIDSignIn.sharedInstance.signIn(withPresenting: view.getRootViewController()) { signResult, error in

    if let error = error {
       //...
       return
    }

     guard let user = signResult?.user,
           let idToken = user.idToken else { return }

     let accessToken = user.accessToken

     let credential = GoogleAuthProvider.credential(withIDToken: idToken.tokenString, accessToken: accessToken.tokenString)

    // Use the credential to authenticate with Firebase

}

guard let clientID = FirebaseApp.app()?.options.clientID else { return }
let config = GIDConfiguration(clientID: clientID)
GIDSignIn.sharedInstance.configuration = config
GIDSignIn.sharedInstance.signIn(withPresenting: view.getRootViewController()) { signResult, error in
if let error = error {
//...
return
}
guard let user = signResult?.user,
let idToken = user.idToken else { return }
let accessToken = user.accessToken
let credential = GoogleAuthProvider.credential(withIDToken: idToken.tokenString, accessToken: accessToken.tokenString)
// Use the credential to authenticate with Firebase
}
