Erro ao ir para tela de detalhes

Ao terminar de implementar a segunda aula do módulo 3 do curso iOS Layout parte 2, estou recebendo esse erro bem estranho sempre que clico em uma célula da TableView de viagens. O correto seria ao clicar, ir para tela de detalhes. Qual seria a solução para esse problema?

Segue o código da minha ViewControler
