This is my interface

import Foundation
import GoogleSignIn
import UIKit
import ComposeApp

// This class implements the GoogleSignInPlatform interface from Kotlin
class GoogleSignInBridge: GoogleSignInPlatform {

    guard let currentUser = GIDSignIn.sharedInstance.currentUser else {
      completionHandler( nil , nil)
    }
     
    // Extract user information
    let userId = currentUser.userID ?? ""
    let email = currentUser.profile?.email ?? ""
    let displayName = currentUser.profile?.name ?? ""
    let photoUrl = currentUser.profile?.imageURL(withDimension: 200)?.absoluteString
    let idToken = currentUser.idToken?.tokenString
     
    // Create and return GoogleUserInfo

This is my swift code
