                    "category_name": "Home Care",
                    "category_id": 3,
                    "have_sub_category": false,
                    "sub_categories": []
                }
            ]
        }
    ],
    "cart_items_count": 5,

    "is_authenticated": true,
    "new_notification_count": 1,
    "cash_back_msg": "Dummy Cash Back message"
}

我创建了一个..但显示错误

struct Home2Response: Codable {
    var status, error: Bool?
    var data: [Home2ResponseDatum]?
    var cartItemsCount, totalCartPrice: Int?
    var isAuthenticated: Bool?
    var newNotificationCount: Int?
    var cashBackMsg: String?

    enum CodingKeys: String, CodingKey {
        case status, error, data
        case cartItemsCount = "cart_items_count"
        case totalCartPrice = "total_cart_price"
        case isAuthenticated = "is_authenticated"
        case newNotificationCount = "new_notification_count"
        case cashBackMsg = "cash_back_msg"
    }
}

// MARK: - Home2ResponseDatum
struct Home2ResponseDatum: Codable {
    var type: Int?
    var title: String?
    var datumDescription: String?
    var data: [Any]?

    enum CodingKeys: String, CodingKey {
        case type, title
        case datumDescription = "description"
        case data
    }
}

【问题讨论】：

您不能将Any 与Codable 一起使用。为 data Array 使用特定类型，不要使用 Any。
data 的合理解决方案是一个枚举，其关联类型取决于 type。
你可能想看看app.quicktype.io
在线发帖提示：“.but 显示错误” 什么错误？显示错误，以及哪一行。您应该有更快的答案，我们不必阅读所有内容，并找出小错误

【解决方案1】：

JSON 中的名称应与struct 中的名称匹配。将 datumDescription 更改为描述。

struct Data : Codable {
    let type : Int?
    let title : String?
    let description : String?
    let data : [Data]?

【讨论】：

OP 使用 CodingKey 枚举，所以这不是问题。
