Ios swift – Why doesn't UITextfield bind value when selected `My Own Password` after field is autofilled?

This is how I define actions for my password UITextFields:

mainView.passwordTextField.rx.text.orEmpty.bind(to: viewModel.password).disposed(by: disposeBag)

mainView.passwordTextField.rx.controlEvent([.editingChanged])
        .asObservable()
        .subscribe { [mainView, viewModel, weak self] ale in
            print(">>>>>")
            print(viewModel.password.value)
            self?.updateView()
        }.disposed(by: disposeBag)

And this is how it look like after password autofill is called there:

>>>>>>

And when I select from suggest autopassword My own password all fields are reset and are empty, but nothing is called. And in viewModel.password.value there is still previous non empty value. How can I resolve it?

    editingChanged is described as "touch event" in UIKit doc. So the system-provided autofill may be simulating touches. The field clearing effect of "My own password" then probably does not simulate touches. Try observe some other control events not related to touches, ultimately allEvents.

    Thought #2: or subscribe to the text itself, not to the control events.

    I’m not sure entirely what the problem is based on the description but please be aware that .rx.text and .rx.controlEvent() only report changes made by the user, not changes made programmatically. Maybe that is the confusion you are having?

    Also, the code you post doesn’t make too much sense. You are already binding the changes in passwordTextField to the view model’s password property (I assume it’s a BehaviorRelay). So why read from it in the subscribe when you are already writing to it in a different subscribe? You can’t really be sure which subscribe’s closure will be called first.
