Swift集成Firebase后Facebook登录提示App ID未找到求助

近期在Swift项目中集成了Firebase，此前Facebook登录功能正常，但现在App能正常启动，点击登录按钮却崩溃，提示无法找到Facebook App ID，尽管该ID已配置在Info.plist中。已按照文档将FirebaseAppDelegateProxyEnabled设为NO以禁用方法混编，但问题仍未解决。调试后发现Facebook的App Delegate从未被调用，尝试了多种网上的解决方案均无效，恳请各位提供帮助。

以下是相关配置及代码：

App Delegate代码 #

class AppDelegate: NSObject, UIApplicationDelegate {
    func application(
            _ application: UIApplication,
            didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?

        ApplicationDelegate.shared.application(app, open: url, options: options)
        return true

    }
    
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
      // 将设备令牌传递给认证服务
      Auth.auth().setAPNSToken(deviceToken, type: .prod)

      // 根据App需求进一步处理设备令牌
      // ...
    }
}

登录视图相关代码 #

struct FBLog: UIViewRepresentable {
    
    @Binding var logged: Bool
    @Binding var email: String
    
    func makeCoordinator() -> FBLog.Coordinator {
        return FBLog.Coordinator(parent1: self)
    }
    
    func makeUIView(context: Context) -> FBLoginButton{
        let button = FBLoginButton()
        
        button.permissions = ["public_profile", "email"]
        
        button.delegate = context.coordinator
        
        return button
    }
    
    func updateUIView(_ uiView: FBLoginButton, context: Context){
        
    }
    
    class Coordinator : NSObject, LoginButtonDelegate{
        
        var parent : FBLog
        
        init(parent1: FBLog){
            parent = parent1
        }
        
        func loginButtonDidLogOut(_ loginButton: FBLoginButton) {

            parent.email = ""
        }
        
        func loginButton(_ loginButton: FBLoginButton, didCompleteWith result: LoginManagerLoginResult?, error: Error?){            
            if error != nil {
                print(error!.localizedDescription)
                return

            if !(result!.isCancelled) {
                // 自定义业务代码
            }
        }
    }
}

FBLog的调用方式 #

struct SignUpView: View {
@State var logged = false
@State var creatingAccount = false
@State var email: String = ""
@State var creationError = false
@State var logged_in_with = ""
@StateObject private var store = UserStore()
let dummyError = CreationError.basic

var body: some View {
    VStack {
        if logged {
            if creatingAccount {
                CreateAccountView()
            } else {
                MainPage()
            }
        } else {
