Can't get email from facebook using fast 3 and ios 10

Question

Hi, I am trying to get my email from facebook since I play on iOS sdk in facebook using swift. The iOS platform is 10, fast 3, and Xcode 8. I have been following online tutorials, but I am having trouble getting email.

below is my code:

if FBSDKAccessToken.current() == nil { print("I got token") let fbButton = FBSDKLoginButton() fbButton.readPermissions = ["public_profile", "email", "user_friends"] view.addSubview(fbButton) fbButton.center = view.center fbButton.delegate = self self.fetchprofile() } else { print("Dont have token") let loginView : FBSDKLoginButton = FBSDKLoginButton() self.view.addSubview(loginView) loginView.center = self.view.center loginView.readPermissions = ["public_profile", "email", "user_friends"] loginView.delegate = self } func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) { if error != nil { print(error.localizedDescription) return } print("I'm in") fetchprofile() } func fetchprofile() { print("Getting profile") let parameters = ["fields": "email"] let graphRequest:FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: parameters, httpMethod: "GET") graphRequest.start(completionHandler: {(connection, result, error) -> Void in if error != nil { print("Error retrieving details: \(error?.localizedDescription)") return } guard let result = result as? [String:[AnyObject]], let email = result["email"] else { return } print("Email: \(email)\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n") self.view.backgroundColor = UIColor.red }) } 

and in my appdelegate.swift file:

  //have both google and facebook signin. Google works but facebook doesn't func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return GIDSignIn.sharedInstance().handle(url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String, annotation: options[UIApplicationOpenURLOptionsKey.annotation]) || FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String, annotation: options[UIApplicationOpenURLOptionsKey.annotation]) } 

I can log in and log out, but I cannot receive an email.

UPDATE Actually, when I actually send print (email), I can see it on the console as an optional operator. I'm having trouble displaying it without an extra record

Answer 1

I solved the problem this way:

 func fetchProfile(){ FBSDKGraphRequest(graphPath: "/me", parameters: ["fields" : "email, name, id, gender"]) .start(completionHandler: { (connection, result, error) in guard let result = result as? NSDictionary, let email = result["email"] as? String, let user_name = result["name"] as? String, let user_gender = result["gender"] as? String, let user_id_fb = result["id"] as? String else { return } }) } 

Answer 2

This solution worked for me without the "/" parameter in the graphPath parameter!
FBSDKGraphRequest (graphPath: "me" .....
