import UIKit

class MealsTableViewController : UITableViewController {

    var meals = [Meal(name: "Salada", happiness: 2),
                 Meal(name: "Sopa", happiness: 5)]

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return meals.count
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let row = indexPath.row
        let meal = meals[row]
        let cell = UITableViewCell(style: <#T##UITableViewCellStyle#>, reuseIdentifier: nil)
        cell.textLabel!.text = meal.name
    }

}
