Answer 1

Updated for RxSwift 3 and improved throttle operator

With new behavior of throtlle operator, introduced in RxSwift 3.0.0-beta.1, you can use it just like that:

    downloadButton.rx.tap
    .throttle(3, latest: false, scheduler: MainScheduler.instance)
    .subscribe(onNext: { _ in
        NSLog("tap")
    }).addDisposableTo(bag)

Old version of answer

Use window operator and then transform Observable> to flat Observable using flatMap.

This sample code prints 'tap' only for first tap in every 3 seconds windows (or if tap count exceeds 10000).

    downloadButton.rx_tap
    .window(timeSpan: 3, count: 10000, scheduler: MainScheduler.instance)
    .flatMap({ observable -> Observable in
        return observable.take(1)
    })
    .subscribeNext { _ in
        NSLog("tap")
    }.addDisposableTo(bag)
