protocol LangSelectedDataPassing
{
    var dataStore: SelectLanguageDataStore? { get }
}

class RouterSelectLanguage: NSObject, ListLanguageRoutingLogic, LangSelectedDataPassing
{
    weak var viewControllerSL: ViewControllerSelectLanguage?
    var dataStore: SelectLanguageDataStore?
    func routeToStartPage(segue: UIStoryboardSegue?) {
        let destinationVC = segue!.destination as! ViewControllerStartPage
        var destinationDS = destinationVC.startPageRouter!.dataStore!
        passDataToStartPage(source: dataStore!, destination: &destinationDS)

    }

    // MARK: Passing data
    func passDataToStartPage(source: SelectLanguageDataStore, destination: inout StartPageDataStore)
    {
        let selectedRow = viewControllerSL?.tblView.indexPathForSelectedRow?.row
        destination.langSelected = source.langs?[selectedRow!]
    }
}
