swift 无法在集合视图中使用 api 数据

我的 JSON 是 -

    {
    "status": "success",
    "data": [
        {
            "_id": "15756323",
            "name": "A",
            "icons": "https://sdfgsuew34j.png",
            "createdAt": "2021-03-18T13:06:44.054Z",
            "updatedAt": "2021-03-18T13:06:44.054Z",
            "__v": 0,
            "id": "6053503drm476"
        },
        {
            "_id": "45646054821",
            "name": "S",
            "icons": "https://dkj/djf.png",
            "createdAt": "2021-03-19T10:51:07.066Z",
            "updatedAt": "2021-03-19T10:51:07.066Z",
            "__v": 0,
            "id": "6054821b11kd6873"
        }
]
  }

我正在尝试在 collectionView 中打印 API 数据 这是一些代码

    var places: [Post]?
       func apicall() {
            
            let url = URL(string: "http://17.550.457.84/api/category/list")!
            URLSession.shared.dataTask(with: url) { (data, response, error) in
                
                if error == nil {
    
                do {
                    self.places = try JSONDecoder().decode([Post].self, from: data! )
                  
                } catch {
                    print("Error during JSON serialization: \(error.localizedDescription)")
                }
                
            }
        }.resume()
    }

我在调试器中收到一条消息 -> JSON 序列化期间出错：无法读取数据，因为格式不正确。

我也尝试改变->self.places = try JSONDecoder().decode([Post].self，来自：数据！ )` 到

self.places = try JSONDecoder().decode(Post.self, from: data! )

然后我收到错误 -> 无法将“Post”类型的值分配给“[Post]”类型？

这是我的模型类

struct Post : Codable {
    let _id : String?
    let name : String?
    let icons : String?
    let createdAt : String?
    let updatedAt : String?
    let __v : Int?
    let id : String?
    
    enum CodingKeys: String, CodingKey {
        
        case _id = "_id"
        case name = "name"
        case icons = "icons"
        case createdAt = "createdAt"
        case updatedAt = "updatedAt"
        case __v = "__v"
        case id = "id"
    }

错误消息基本上是“您的模型和即将到来的数据模型（JSON）不相等”。您需要更改您的模型，例如：

struct BaseModel : Codable{
   var status : String?
   var data : [Post]?
}

当您尝试反序列化它时，您需要创建该 BaseModel 的实例，以便

    var baseModel: BaseModel?
    var places: [Post]?
 

当响应成功时

 do {
       let responseData = try JSONDecoder().decode(BaseModel.self, from: data! )
        self.places = responseData.data!
              
 } catch {              

        print("Error during JSON serialization: \(error.localizedDescription
   }
