How to Detect When User Used Password Autofill on a Uitextfield

Password autofill is not working in swift

Try naming your text fields serially txt1 txt2 txt3 txt4 tt5 txt6

override func viewDidLoad() {
 super.viewDidLoad()
 txt1.becomeFirstResponder()
}

 func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
        if ((textField.text?.count)! < 1 ) && (string.count > 0) {
            if textField == txt1 {
                txt2.becomeFirstResponder()

            }

            if textField == txt2 {
                txt3.becomeFirstResponder()

            }

            if textField == txt3 {
                txt4.becomeFirstResponder()
            }

            if textField == txt4 {
                txt5.becomeFirstResponder()
            }
            if textField == txt5 {
                txt6.becomeFirstResponder()
            }
            if textField == txt6{
                txt6.becomeFirstResponder()
            }

            textField.text = string
            return false
        } else if ((textField.text?.count)! >= 1) && (string.count == 0) {
            if textField == txt2 {
                txt1.becomeFirstResponder()
            }
            if textField == txt3 {
                txt2.becomeFirstResponder()

            }
            if textField == txt4 {
                txt3.becomeFirstResponder()
            }

           if textField == txt5 {
                txt4.becomeFirstResponder()
            }
            if textField == txt6 {
                txt5.becomeFirstResponder()
            }
            if textField == txt1{
               txt6.resignFirstResponder()
            }

            textField.text = ""
            return false
        } else if (textField.text?.count)! >= 1 {
            textField.text = string
            return false
        }

        return true
    }

Happy Coding

Why does the Apple-generated strong password autofill have no text?

It was because on my UITextField .clearsOnBeginEditing was set to true. Whenever the text input became first responder it would clear the existing text, including the Apple generated strong password.

Not sure how to have .clearsOnBeginEditing and use a Apple generated password though.

Is it possible to modify the AutoFill string before showing in textfield?

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

where replacementString is your answer
