这是我的json:
[
{
"question": "What is the name of your favorite teacher?",
"id": "Q1.1",
"created_at": null,
},
{
"question": "What is the name of your favorite singer?",
"id": "Q1.2",
"created_at": null,
},
{
"question": "What is the name of your favorite teacher?",
"id": "Q1.3",
"created_at": null,
}
]
如何使用Codable解析它?我的结构应该是什么?
