CustomCell está vazio ou resulta em erro SIGABRT [W / Code]

Estou tentando criar um player de vídeo que exiba em um UITableView as miniaturas, títulos e descrições dos vídeos. Quando o usuário clica no raw, ele abre uma nova exibição com um WebView onde o vídeo será reproduzido.

No momento, ainda estou tentando definir a célula personalizada. Estou recebendo um erro noAppDelegate.swift arquivo noclass AppDelegate: UIResponder, UIApplicationDelegate { linha e o erro é:Thread 1: signal SIGABRT. O log de erros está no final desta postagem.

NoMain.storyboard Adicionei um TableView (que eu conectei ao ViewController com odelegate edataSource) com uma célula protótipo, onde adicionei um ImageView e dois rótulos. Eu também criei um arquivo Swift chamadoCustomTableViewCell.swift. Eu ajustei oView Controller Classe personalizada para ViewController, o identificador da célula acustomCell, estilo "Custom" e classe paraCustomTableViewCell.

NoViewController.swift Criei uma matriz com as informações dos vídeos e defino as funções da tabela.

Também tentei outras maneiras de escrever o código com soluções que encontrei aqui no Stack, mas também recebo o mesmo erro ou, no máximo, recebo uma tabela com 3 células vazias. O código está abaixo. Alguém pode dizer como colocar essas células personalizadas funcionando, por favor?

Desde já, obrigado!
