Estou tentando criar um aplicativo de cartão de memória. Também obtive o aplicativo com sucesso no ponto em que havia 11 matrizes diferentes de flashcards e todas essas matrizes adicionaram uma matriz final pela qual eu poderia passar rapidamente. Como você pode ver, cada grupo tem "ativo: verdadeiro" no final. Isso ocorre porque tenho uma página de configurações para ativar e desativar cada grupo de palavras.

import UIKit

class SecondViewController: UIViewController , UIGestureRecognizerDelegate  {

@IBAction func home(_ sender: Any) {
performSegue(withIdentifier: "home", sender: self)

let list2 = List(words: ["ladder", "ladybug", "laughing", "lawnmower", "lemon", "leopard", "leprechaun", "letters", "licking", "lifesaver", "lifting", "lightbulb", "lightning", "listen", "llama"], active: true)

mas eu precisava adicionar um arquivo de som a cada cartão flash, para que, sempre que o cartão fosse tocado, um arquivo de áudio fosse reproduzido, alterei o código para que cada cartão de cada grupo fosse acoplado a um arquivo de áudio. No entanto, não consegui fazer com que esse novo código funcionasse sem problemas, ele está cheio de bugs. Eu publiquei os erros abaixo. Quando executo o novo código, posso passar por todas as imagens, assim como meu código original, mas isso atualmente não é possível (o novo código está abaixo)
