How to enable/disable OneTimeCode feature for specific text field?

Question

For OTP text field, I have set textContentType as oneTimeCode

if #available(iOS 12.0, *) {
     otpTextField.textContentType = .oneTimeCode
}    

Answer 1

I tried all sorts of content types to prevent OTP from being suggested on the keyboard, finally this one worked

if #available(iOS 12.0, *) {
    textField.textContentType = .username
}

In this case the UITextField is capturing a pin, and also has

keyboardType = .numberPad

Although that may not make a difference
