Facebook login user data in Authentication doesn’t show in firebase consoles - swift

Question

Every time, when I use a Facebook account to log in the application is supposed to have identified email shows up on the Firebase console but it doesn’t work properly. Users can use their Facebook account to access the application, but the problem is my profile page always got a crash when I attempt to make that page shows email of the users up. but if I use an email account to log in it doesn’t have any problem the email that I used to sign up able to shows up normally.
I have done everything in this link but can’t fix this problem.
https://firebase.google.com/docs/auth/ios/facebook-login
On the profile page, I use this code to call the email and user
import UIKit
import Firebase
import FirebaseAuth
import FacebookLogin
import FacebookCore
import FirebaseStorage
class ProfileViewController: UIViewController {
#IBOutlet weak var nameLabel: UILabel!
#IBOutlet weak var emailLabel: UILabel!
#IBOutlet weak var passTextField: UITextField!
#IBOutlet weak var changeNameText: UITextField!
#IBOutlet weak var menuButton: UIBarButtonItem!
#IBOutlet weak var imageProfile: UIImageView!
#IBOutlet weak var alertButton: UIBarButtonItem!
let imageUniqueName = UUID().uuidString
let imagePicker = UIImagePickerController()
override func viewDidLoad() {
super.viewDidLoad()
let user = Auth.auth().currentUser
setUserDataToView(withFIRUser: user!)
customizeNavBar()
sideMenus()
let tapGesture = UITapGestureRecognizer()
tapGesture.addTarget(self, action: #selector(ProfileViewController.openGallery(tapGesture:)))
imageProfile.isUserInteractionEnabled = true
imageProfile.addGestureRecognizer(tapGesture)
imageProfile.drawAsCircle()
}
func setUserDataToView(withFIRUser user: User) {
nameLabel.text = user.displayName
emailLabel.text = "อีเมล์ : \(user.email!)"
}
this is all code on my LoginViewController page
import UIKit
import Firebase
import FirebaseAuth
import FBSDKCoreKit
import FBSDKLoginKit
import FBSDKCoreKit
import FacebookLogin
import FacebookCore
class LoginViewController: UIViewController, FBSDKLoginButtonDelegate {
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
if error != nil {
print("โปรดตรวจสอบใหม่อีกรอบ", error.localizedDescription)
} else if result.isCancelled {
} else {
let credential = FacebookAuthProvider.credential(withAccessToken: FBSDKAccessToken.current().tokenString)
Auth.auth().signInAndRetrieveData(with: credential) { (authResult, error) in
ProgressHUD.showSuccess("ยินดีต้อนรับ")
self.performSegue(withIdentifier: "Main", sender: self)
}
}
}
func loginButtonDidLogOut(_ loginButton: FBSDKLoginButton!) {
ProgressHUD.showSuccess("ออกจากระบบสำเร็จ")
}
let loginButton = FBSDKLoginButton()
//Textfields pre-linked with IBOutlets
#IBOutlet var emailTextfield: UITextField!
#IBOutlet var passwordTextfield: UITextField!
#IBOutlet weak var facebookButton: FBSDKLoginButton!
override func viewDidLoad() {
super.viewDidLoad()
loginButton.delegate = self
loginButton.readPermissions = ["public_profile", "email"]
self.navigationController?.setNavigationBarHidden(true, animated: false)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func logInPressed(_ sender: AnyObject) {
//TODO: Log in the user
Auth.auth().signIn(withEmail: emailTextfield.text!, password: passwordTextfield.text!) { (user, error) in
if error != nil{
let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
print(error!)
}else{
ProgressHUD.showSuccess("ยินดีต้อนรับ")
self.performSegue(withIdentifier: "Main", sender: self)
}
}
}
#IBAction func onClickPassword(_ sender: Any) {
if self.passwordTextfield.isSecureTextEntry == true {
self.passwordTextfield.isSecureTextEntry = false
}
else {
self.passwordTextfield.isSecureTextEntry = true
}
}
override func viewDidAppear(_ animated: Bool){
super.viewDidAppear(animated)
if Auth.auth().currentUser != nil {
self.performSegue(withIdentifier: "Main", sender: nil)
}
}
}
