import UIKit
import Eureka

class UserInfoViewController: FormViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        form +++ Section("Personal Info") .       <--- Here is the error showing "use of unresolved identifier".

            <<< TextRow() { row in
                row.title = "Username"
                row.placeholder = "Username"
            }

            <<< TextRow() { row in
                row.title = "Password"
