How to detect when user used Password AutoFill on a UITextField

Question

I\'ve implemented all the app and server changes necessary to support Password Autofill on iOS 11, and it works well. I\'d like it to work a little better.

Answer 1

Swift 5:

The following delegate method gets triggered every time that the user types something in the textfield. That string count is usually one, so any number great than that is either autofill or the user pasting some text into the field. I am only using this delegate on this password field.

extension LoginView: UITextFieldDelegate {

    func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
        if string.count > 1 {
            DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(1)) { [weak self] in
                self?.endEditing(true)
            }
        }
        return true
    }
}
