Get email and name Facebook SDK v4.4.0 Swift

I've used fields in android, so I figured to try it in iOS as well, and it works.

let req = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"email,name"], tokenString: accessToken.tokenString, version: nil, HTTPMethod: "GET")
   req.startWithCompletionHandler({ (connection, result, error : NSError!) -> Void in
       if(error == nil) {
            print("result \(result)")
       } else {
            print("error \(error)")
       }
   }
)

result will print:

result {
   email = "[email protected]";
   id = 123456789;
   name = "Your Name";
}

Found that these fields are equal to the User endpoint, see this link where you can see all the fields that you can get.

Update for Swift 4 and above

let r = FBSDKGraphRequest(graphPath: "me",
                          parameters: ["fields": "email,name"],
                          tokenString: FBSDKAccessToken.current()?.tokenString,
                          version: nil,
                          httpMethod: "GET")

r?.start(completionHandler: { test, result, error in
    if error == nil {
        print(result)
    }
})

Update for Swift 5 with FBSDKLoginKit 6.5.0

guard let accessToken = FBSDKLoginKit.AccessToken.current else { return }
let graphRequest = FBSDKLoginKit.GraphRequest(graphPath: "me",
                                              parameters: ["fields": "email, name"],
                                              tokenString: accessToken.tokenString,
                                              version: nil,
                                              httpMethod: .get)
graphRequest.start { (connection, result, error) -> Void in
    if error == nil {
        print("result \(result)")
    }
    else {
        print("error \(error)")
    }
}

For Swift 3 & Facebook SDK 4.16.0:

func getFBUserInfo() {
    let request = GraphRequest(graphPath: "me", parameters: ["fields":"email,name"], accessToken: AccessToken.current, httpMethod: .GET, apiVersion: FacebookCore.GraphAPIVersion.defaultVersion)
    request.start { (response, result) in
        switch result {
        case .success(let value):
            print(value.dictionaryValue)
        case .failed(let error):
            print(error)
        }
    }
}

and will print:

Optional(["id": 1xxxxxxxxxxxxx, "name": Me, "email": [email protected]])

Swift 5

Will retrieve the user email, first name, last name & their id by using the GraphRequest class:

// Facebook graph request to retrieve the user email & name
let token = AccessToken.current?.tokenString
let params = ["fields": "first_name, last_name, email"]
let graphRequest = GraphRequest(graphPath: "me", parameters: params, tokenString: token, version: nil, httpMethod: .get)
graphRequest.start { (connection, result, error) in

    if let err = error {
        print("Facebook graph request error: \(err)")
    } else {
        print("Facebook graph request successful!")

        guard let json = result as? NSDictionary else { return }
        if let email = json["email"] as? String {
            print("\(email)")
        }
        if let firstName = json["first_name"] as? String {
            print("\(firstName)")
        }
        if let lastName = json["last_name"] as? String {
            print("\(lastName)")
        }
        if let id = json["id"] as? String {
            print("\(id)")
        }
    }
}

let request = GraphRequest.init(graphPath: "me", parameters: ["fields":"first_name,last_name,email, picture.type(large)"], accessToken: AccessToken.current, httpMethod: .GET, apiVersion: FacebookCore.GraphAPIVersion.defaultVersion)

request.start({ (response, requestResult) in
      switch requestResult{
          case .success(let response):
             print(response.dictionaryValue)
          case .failed(let error):
             print(error.localizedDescription)
      }
})
