iOS: textField on UIAlertController becoming first responder on alert present

Question

I am adding textField to UIAlertController with the code below:

let anAlertController = UIAlertController(title:title, message:message, preferredStyle: .alert)
        weak var weakSelf = self

        let aDefaultAction = UIAlertAction(title:defaultTitle, style: UIAlertAction.Style.default) {
            UIAlertAction in

        anAlertController.addAction(aDefaultAction)
    }

    let aCancelAction = UIAlertAction(title:canceltTitle, style: UIAlertAction.Style.cancel) {
        UIAlertAction in
    }
    anAlertController.addAction(aCancelAction)

    anAlertController.addTextField { (textField) in
        textField.textAlignment = NSTextAlignment.center
        textField.text = "textFieldText"
        textField.delegate = self
        textField.resignFirstResponder()
    }
    self.present(anAlertController, animated: true, completion: nil)

When i try to present UIAlertController, textfield becoming first responder automatically. I don’t want textfield should become first responder while presenting alert. i Googled and tried several ways to avoid this but no luck. Can anybody tell how to achieve this?

Are you sure you not missing something? Checked on simulator and device (iOS 12), all works. — Gralex, Feb 06 '19 at 10:01

try this

anAlertController.addTextField { (textField) in
        textField.textAlignment = .center
        textField.text = "textFieldText"
        textField.delegate = self as? UITextFieldDelegate
        textField.isEnabled = false

    }
    self.present(anAlertController, animated: false, completion: {
        if let getTextfield  = anAlertController.textFields?.first{
                getTextfield.resignFirstResponder()
                getTextfield.isEnabled = true
        }

    })

@Anbu.Karthik Thanks its working fine, but when i touch the textfield keyboard popsup now. How to stop keyboard popup on textfield touch but touch enabled – Logger Feb 06 '19 at 10:13
@lazyCoder delegate can implement method `textFieldShouldBeginEditing` with `false` result. No need to enable\disable textFiled in this case. – Gralex Feb 06 '19 at 10:31

You can disable UITexField for a while, it can't be responder on alert appear:

anAlertController.addTextField { (textField) in
    textField.textAlignment = NSTextAlignment.center
    textField.text = "textFieldText"
    textField.isEnabled = false
    DispatchQueue.main.async { textField.isEnabled = true }
}
