RxSwift obtain value from one item in Observable sequence

Question

I'm trying to gradually convert my App to RxSwift / MVVM. But I think I'm doing some things incorrectly.

In this example I have a static table with this specific information.

    let itens = Observable.just([
        MenuItem(name: GlobalStrings.menuItemHome,      nameClass: "GPMainVC"),
        MenuItem(name: GlobalStrings.menuItemProfile,   nameClass: "GPMainVC"),
        MenuItem(name: GlobalStrings.menuItemLevels,    nameClass: "GPLevelsVC"),
    ])

I need to know the model(MenuItem) and the index when the user select a cell, but I am having trouble doing that

 tableView.rx
        .itemSelected
        .map { [weak self] indexPath in
            return (indexPath, self?.modelView.itens.elementAt(indexPath.row))
        }
        .subscribe(onNext: { [weak self] indexPath, model in

            self?.tableView.reloadData()

            //can´t get MenuItem because model its a observable
            //self?.didSelect((indexPath as NSIndexPath).row, name.nameClass)

        })
        .addDisposableTo(disposeBag)

Thanks in advance

You have to do next steps:

1. Use Variable. I think it's a better solution in your situation.

   let itens = Variable([
       MenuItem(name: GlobalStrings.menuItemHome, nameClass: "GPMainVC"),
       MenuItem(name: GlobalStrings.menuItemProfile, nameClass: "GPMainVC"),
       MenuItem(name: GlobalStrings.menuItemLevels, nameClass: "GPLevelsVC"),
   ])
   

2. Use the following code if you want to get index and model from a clicked cell.

   tableView.rx
   .itemSelected
   .map { index in
       return (index, self.items.value[index.row])
   }
   .subscribe(onNext: { [weak self] index, model in
       // model is MenuItem class
   })
   .addDisposableTo(disposeBag)
