In Swift 4.2 and Xcode 10.1

@IBAction func onClickFBSign(_ sender: UIButton) {

    if let accessToken = AccessToken.current {
        // User is logged in, use 'accessToken' here.
        print(accessToken.userId!)
        print(accessToken.appId)
        print(accessToken.grantedPermissions!)
        print(accessToken.expirationDate)

        let request = GraphRequest(graphPath: "me", parameters: ["fields":"id,email,name,first_name,last_name,picture.type(large)"], 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)
            }
        }

        let storyboard = self.storyboard?.instantiateViewController(withIdentifier: "SVC") as! SecondViewController
        self.present(storyboard, animated: true, completion: nil)
    } else {

        let loginManager=LoginManager()

        loginManager.logIn(readPermissions: [ReadPermission.publicProfile, .email, .userFriends, .userBirthday], viewController : self) { loginResult in
            switch loginResult {
            case .failed(let error):
                print(error)
            case .cancelled:
                print("User cancelled login")
            case .success(let grantedPermissions, let declinedPermissions, let accessToken):
                print("Logged in : \(grantedPermissions), \n \(declinedPermissions), \n \(accessToken.appId), \n \(accessToken.authenticationToken), \n \(accessToken.expirationDate), \n \(accessToken.userId!), \n \(accessToken.refreshDate), \n \(accessToken.grantedPermissions!)")

                let request = GraphRequest(graphPath: "me", parameters: ["fields": "id, email, name, first_name, last_name, picture.type(large)"], 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)
                    }
                }

                let storyboard = self.storyboard?.instantiateViewController(withIdentifier: "SVC") as! SecondViewController
                self.navigationController?.pushViewController(storyboard, animated: true)

            }
        }
    }
