Answer 1

Try this logic hope this will solve your problem
let dict = [NSIndexPath: String]()
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
if let _ = // dict contains value at indexpath {
cell.accessoryType = .Checkmark
} else {
cell.accessoryType = .None
}
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if ( // dict contains value == indexpath) {
// remove value from dict
} else {
//add value to dict
}
tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic)
}

Answer 2

Just take the advantage of prepareForReuse method of UITableViewCell. In your FoodTableViewCell class implement the prepareForReuse menthod like following
class FoodTableViewCell: UITableViewCell
{
override func awakeFromNib()
{
super.awakeFromNib()
// Initialization code
}
override func setSelected(selected: Bool, animated: Bool)
{
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
override func prepareForReuse()
{
self.accessoryType = UITableViewCellAccessoryType.none
//add code to reset selection if there is any other selection mechanism
}
}
