FB LogIn returning Null name iOS Swift

Hey guys! Thanks for this great platform.

Im implementing FB login through your tutorial using FB SDK. It´s “working” but the user being returned has name = “<null>”; Therefore when I try to access it I get a nil object.
When I directly print it from the FB I get: name = “An\U00edbal Alejandro Madrid”;
My name is Aníbal Alejandro Madrid. I guess the í could be messing it up?
This is the field mapping im using:

let fieldsMapping = [

“id” : “facebookId”,

“name” : “name”,

“birthday”: “birthday”,

“first_name”: “fb_first_name”,

“last_name” : “fb_last_name”,

“gender”: “gender”,

“email”: “email”

]

Hi Anibal,

I just checked this issue - FB Login works fine for me.

Here is my sample code.
AppDelegate.m:

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {


    var window: UIWindow?
    
    let APP_ID = "1C5B19B3-953D-9548-FF59-95999A2FE800"
    let SECRET_KEY = "CE0A96CD-0421-B988-FF80-E16A6A8F7200"
    let VERSION_NUM = "v1"
    
    var backendless = Backendless.sharedInstance()
    
    func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
        
        print("AppDelegate -> application:openURL: \(url.scheme)")
        
        let result = FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
        if result {
            
            let token = FBSDKAccessToken.currentAccessToken()
            let fieldsMapping = [
                "id" : "facebookId",
                "name" : "name",
                "birthday": "birthday",
                "first_name": "first_name",
                "last_name" : "last_name",
                "gender": "gender",
                "email": "email"
            ]
            
            backendless.userService.loginWithFacebookSDK(
                token,
                fieldsMapping: fieldsMapping,
                response: { (user: BackendlessUser!) -> Void in
                    print("user: \(user)")
               },
                error: { (fault: Fault!) -> Void in
                    print("Server reported an error: \(fault)")
            })
        }
        
        return result
    }


    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        
        backendless.initApp(APP_ID, secret:SECRET_KEY, version:VERSION_NUM)


        return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
    }
}

ViewController.m:

class ViewController: UIViewController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        let loginButton = FBSDKLoginButton()
        loginButton.center = self.view.center
        self.view.addSubview(loginButton)
    }
}

Here is app log (you can see all mapped fields which are returned by server):

and my Backendless app dashboard:

You should download the latest release of libs from github:

  • backendless
  • CommLibiOS
    and try again.
    Also you could try my sample code with my appID & secretKey (here above).
