Swift 4 JSON可编码ID作为键

swift

我想将Swift 4的可编码功能与json一起使用，但其中一些键没有设置名称。而是有一个数组，它们是像

{
 "status": "ok",
 "messages": {
   "generalMessages": [],
   "recordMessages": []
 },
 "foundRows": 2515989,
 "data": {
   "181": {
     "animalID": "181",
     "animalName": "Sophie",
     "animalBreed": "Domestic Short Hair / Domestic Short Hair / Mixed (short coat)",
     "animalGeneralAge": "Adult",
     "animalSex": "Female",
     "animalPrimaryBreed": "Domestic Short Hair",
     "animalUpdatedDate": "6/26/2015 2:00 PM",
     "animalOrgID": "12",
     "animalLocationDistance": ""

您会在其中看到181个ID。有人知道如何处理181，以便我将其指定为密钥吗？该数字可以是任何数字，并且每个数字都不相同。

想要这样的事情

struct messages: Codable {
    var generalMessages: [String]
    var recordMessages: [String]
}

struct data: Codable {
    var
}

struct Cat: Codable {
    var Status: String
    var messages: messages
    var foundRows: Int
    //var 181: [data] //What do I place here
}

提前致谢。

请检查：

struct ResponseData: Codable {
    struct Inner : Codable {
        var animalID   : String
        var animalName : String

        private enum CodingKeys : String, CodingKey {
            case animalID     = "animalID"
            case animalName   = "animalName"
        }
    }

    var Status: String
    var foundRows: Int
    var data : [String: Inner]

    private enum CodingKeys: String, CodingKey {
        case Status = "status"
        case foundRows = "foundRows"
        case data = "data"
    }
}

let json = """
    {
        "status": "ok",
        "messages": {
            "generalMessages": ["dsfsdf"],
            "recordMessages": ["sdfsdf"]
        },
        "foundRows": 2515989,

            }
        }
    }

let data = json.data(using: .utf8)!
let decoder = JSONDecoder()

        print(key)
        print(value.animalID)
        print(value.animalName)
    }
