How to observe text change in UITextField using RxSwift?

I want to observe any change of the UITextField.text property using RxSwift.

I trying to use rx.text property, but it called only when I set text property like this: textField.text = "", but not working when I typing text.

Also I tried to use rx.observe(String.self, "text"), but it gives the same result.

How can I observe any change of the text in UITextField?

To observe any change of the text in UITextField you can create extension for Reactive class:

public extension Reactive where Base: UITextField {

    public var textChange: Observable<String?> {
        return Observable.merge(self.base.rx.observe(String.self, "text"),
                                self.base.rx.controlEvent(.editingChanged).withLatestFrom(self.base.rx.text))
    }

}
