How to achieve that placeholder text disappears character by character in UITextField

Question

Can you please help me.

In UITextField when we provide a placeholder text its placeholder string will be gone when we enter any character. How can I achieve

Instead of using placeholder text, use a UILabel below your textfield and give the same font style to both. the label text should be like "- - - - -"

And when user starts typing on textfield give a space after each character press.

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {

    if textField.text?.characters.count == 0 && string.characters.count != 0 {
        textField.text = textField.text! + " "
    }
     else {
        return false
    }

    if textField.text?.characters.count == 1 && string.characters.count != 0 {
        textField.text = textField.text! + " "
    }
    else {
        return false
    }

    if textField.text?.characters.count == 2 && string.characters.count != 0 {
        textField.text = textField.text! + " "
    }
    else {
        return false
    }
    if textField.text?.characters.count == 3 && string.characters.count != 0 {
        textField.text = textField.text! + " "
    }
    else {
        return false
    }

    return true
}
