Hot to get model from indexPath in a Rx way

• Two ways to get model from indexPath of TableView & CollectionView
  • Use indexPath and dataSource to get model

    • Observable.just(indexPath).withLatestFrom(#ObservableThatBindToYourTableView) { indexPath, datas in
      return datas[indexPath.secion][indexPath.row]
      }
      

  • Use model(at: indexPath)

    • do {
      let element: Type = try tableView.model(at: indexPath)
      } catch {
      //work with error when cast failed
      }
      

    • Warning: You must specify the type of your variable.

    • Your can first transform the data to Any and then downcast to the type of your Model or Protocol

      let e: Any = try tableView.model(at: indexPath)
      if let t = e as? Type {
        t.foo()
      }
