Declaration

func textField(at textFieldIndex: Int) -> UITextField?

textFieldIndex: The index of the text field. The text field indices start at 0.

The text field specified by index textFieldIndex.

The number of text fields present in an alert is dependent on the style of the alert.

Alert Style	Text Fields
`UIAlertViewStyle.default`	No user-editable text fields.
`UIAlertViewStyle.secureTextInput`	A single text field at index `0`.
`UIAlertViewStyle.plainTextInput`	A single text field at index `0`.
`UIAlertViewStyle.loginAndPasswordInput`	The login field is at index `0`. The password field is at index `1`.

If your application attempts to retrieve a text field with an index that is out of bounds, the alert raises an rangeException.
