I have a table view with RxDataSources on which cell items got a remove icon. when cells get dequeued and click on that remove icon, all the previous click events get triggered, thus duplicate tap. Item cell :

 removeImageView.rx.tap().map { _ in indexPath } 
            .bind(to: viewModel.onRemoveItem).disposed(by: cellDisposeBag)

Cell viewmodel:

let onRemoveItem = PublishSubject<IndexPath>()

View controller view model where the cell and ViewModel get bound:

 let vm = ItemViewModel(with: item)
            vm.onRemoveItem.bind(to: self.onRemoveItem).disposed(by: self.rx.disposeBag)

            return SectionItem.item(viewModel: vm)

View Controller:

let dataSource = RxTableViewSectionedReloadDataSource<SectionItem>(configureCell: { dataSource, tableView, indexPath, item in
    switch item {
    case .item(let viewModel):
        let cell = (tableView.dequeueReusableCell(withIdentifier: itemtIdentifier, for: indexPath) as? ItemCell)!
        cell.bind(to: viewModel, at: indexPath)
        return cell
    }
}, titleForHeaderInSection: { dataSource, index in
    let section = dataSource[index]
    return section.title
}  )

output?.items
    .bind(to: tableView.rx.items(dataSource: dataSource))
    .disposed(by: rx.disposeBag)

output?.onRemoveCartIemTapped.distinctUntilChanged() 
    .skip(1)
    .distinctUntilChanged().drive(onNext: { [weak self] (indexPath) in
    print("onRemoveCartIemTapped" + String(indexPath.item))
}).disposed(by: rx.disposeBag)

Console debug:

onRemoveCartIemTapped0
onRemoveCartIemTapped3
onRemoveCartIemTapped1
onRemoveCartIemTapped4
