RxSwift/RxCocoa: prevent UITextField from having more than ... characters : <p>I would like to have a UITextField configured with RxSwift/RxCocoa so that it only contains up to ... characters. I do not want to use the <code>UITextFieldDelegate</code> for this but would love to achieve this with RxSwift/RxCocoa. Is there a way to do this?</p>
