I have an array `fruit = ["Apple", "Orange", "Pear", "Kiwi"]` that has Entity FOOD and is presented in an UItableView. Is there a way to make some content undeletable. For example, can I make `"Kiwi"` undeletable. 

Something like, 
`let i = fruit.index(where: "Kiwi")
 let IArr = [0...fruit.count] 
 IArr = IArr.filter{$0 != i}` //deletes the index of Kiwi

```
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IArr) {
    let appDelegate = UIApplication.shared.delegate as! AppDelegate
    let context = appDelegate.persistentContainer.viewContext

    if editingStyle == .delete{
        let FRUIT = fruit[indexPath.row]
        context.delete(FRUIT)

        appDelegate.saveContext()
        do {
            fruit = try context.fetch(FOOD.fetchRequest())
        }
        catch
        {
            print("did not fetch")}
        }
        tableView.reloadData()}

```

However, this doesn't work because `indexPath` cannot take array types.
How can I do this?
