Listando Amiibos com Swift

Listando Amiibos com Swift (Quase sem codificar)

Neste projeto a ideia será consumir uma API simples e pública, de uma maneira rápida e com pouco código.

Vamos conectar pelo Postman, gerar e exportar o código de conexão, com o response vamos mapear para um Objeto que irá nos ajudar no Swift.

No Quicktype colocamos a request e copiamos o código que ele gerou, para mapear os campos.

Por fim no Playground vamos colar ambos código e testar, com uma pequena alteração, para demonstrar como listar os dados da API, e prevenir erros lançando eles no catch.
