I can select rows in tableView.rx but I'm wonder how to get array of final selection. I mean the result array of selecting some rows and then deselecting some rows.

Here's my code:

 Observable.zip(tableView.rx.modelSelected(Country.self), tableView.rx.itemSelected).subscribe(onNext: { (selectedCountry, indexPath) in
            print("2 selected Country is \(selectedCountry) and indexPath is \(indexPath.row)")
            self.selectedCountries.append(selectedCountry)

I want also see selected rows as marked.

I appreciate for your helping. thanks

First you have to use this:

tableView.allowsMultipleSelection = true

Then you could use these to do what ever you want:

  let selectedItems = tableView.rx.modelSelected(Country.self).subscribe { item in
        print("selected: \(item)")
        print("selected rows: \(self.tableView.indexPathsForSelectedRows)")
  }
  let deselectedItems = tableView.rx.modelDeselected(Country.self).subscribe { item in
        print("deselected: \(item)")
  }

This will produce an Observable array of indexPaths:

    tableView.allowsMultipleSelection = true
    
    let selectedItems = Observable.merge(
        tableView.rx.itemSelected.asObservable(),
        tableView.rx.itemDeselected.asObservable()
    )
        .flatMap { [tableView] _ in
            Observable.just(tableView.indexPathsForSelectedRows ?? [])
        }
