ios – Blinking cursor as default in Swift

How can I make cursor blink when the view is opened with out touching wherever. I’m at present utilizing becomeFirstResponder() My textual content area turns into actually first responder however when the view is opened, blink doesn’t blink. Why?

My code is right here.

import UIKit

class ViewController: UIViewController {
    
  //  @IBOutlet weak var resultLabel: UILabel!
    

    
    let resultTextField: UITextField = {
        var myField = UITextField()
        myField.textColor = .blue
        myField.font = .systemFont(ofSize: 36)
        myField.textAlignment = .proper
        myField.borderStyle = .roundedRect
        //myField.textual content = "0"

        
        return myField
    }()
    
    override func viewDidLoad() {
        tremendous.viewDidLoad()
        
        view.addSubview(resultTextField)
        resultTextField.becomeFirstResponder()
        
        resultTextField.inputView = UIView()
                    
    }
    
    
    
    override func viewWillLayoutSubviews() {
        tremendous.viewWillLayoutSubviews()
        
        let myWidth = self.view.body.width
        let myHeight = self.view.body.peak
        
        resultTextField.body = CGRect(x: (myWidth - (myWidth / 1.15))/2,
                                       y: myHeight / 7.5,
                                       width: myWidth / 1.15,
                                       peak: myHeight / 15)
        
    }

}

Thanks
