An error occurred due comparing two variables

Here is my code for login. As you can see, I have my username and password pre defined.

import UIKit

class ViewController: UIViewController {

    @IBOutlet var _username: UITextField!
    @IBOutlet var _password: UITextField!
    @IBOutlet var _login_button: UIButton!
    @IBOutlet var label: UILabel!
    let username = "Kiarash"
    let password = "Test"

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }

    @IBAction func LoginButton(_ sender: Any) {

         if(_username.text == username && _password.text == password)
        {
           label.text = "You are Logged in!"

    }
    }
}

But when I enter the correct username and password, it throw below error. 

unrecognized selector sent to instance 0x7f8b9450ac60
2020-05-03 19:44:02.481826-0700 KCMLogin[9156:552975] *** Terminating app due to uncaught exception 
'NSInvalidArgumentException', reason: '-[UIView setText:]: unrecognized selector sent to instance 0x7f8b9450ac60'

I am not sure why this happen, Sorry I am a beginner.

Remove the current Referencing Outlets from label and reconnect label to view controller.
