У меня есть два пользовательских представления таблицы (не контроллер представления таблицы) с пользовательскими ячейками
.Я хочу выбрать вторую ячейку из MainViewcontroller
и выбрать
заголовок и цена информации о ячейке передаются во второе представление как
меток первой и второй индекса DetailViewController.
Это мой MainViewController.swift
