Вы можете попробовать следующий метод, чтобы сохранить одну ячейку выбранной одновременно
**My arrays**
let section = ["pizza", "deep dish pizza", "calzone"]
let items = [["Margarita", "BBQ Chicken", "Peproni", "BBQ Chicken", "Peproni"], ["sausage", "meat lovers", "veggie lovers"], ["sausage", "chicken pesto", "prawns & mashrooms"]]

/// Initialise the Dictionary

/// Set the Default value as in your case
/// Section - 0 and IndexPath - 0
/// i.e First cell
selectedIndex?.updateValue(0, forKey: 0)
mainTableView.delegate = self
mainTableView.dataSource = self
mainTableView.reloadData()
}

return section.count

return 40
