RxSwift throttle how to get only last value from stream

I'm learning RxSwift, what I would like achieve is to get mechanism which prints me text from UITextFied, but after given interval.

How it works now: when I type first character this character is immediately printed out (not after delay how I expected) and if I keep on typing long sentence, text is printed after each two second (as interval is set in throttle), but I would like to have only latest text value.

My code:

inputField.rx.text.orEmpty
        .throttle(2, latest: true, scheduler: MainScheduler.instance)
        .subscribe(onNext: { text in
            print("\(text)")
        }, onDisposed: nil)
        .addDisposableTo(disposeBag)

Im looking for your help Rx fellows :) Thanks
