RxSwift gets a value from a single element in an observable sequence

Question

I am trying to gradually convert my application to RxSwift / MVVM. But I think I'm doing something wrong.

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 index when the user selects a cell, but I am having problems with this.

 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 need to take the following steps:

• Use a variable. I think this is the best 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"),
  ])
  

• Use the following code if you want to get the 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)
