JSON 序列化错误。 Swift 从 api 响应到 json 的转换错误

Question

来自服务器的数据：

{"status":{"id":5,"title_en":"Accepted By Restaurant","title_restaurant":"In progress","title_rider":"New","title_customer":"In progress","slug":"accepted_by_restaurant","active":1},"orderDetail":{"id":47,"user_customer_id":27,"user_restaurant_id":13,"user_rider_id":null,"coupon_data":null,"order_status_id":5,"cancelled_by":null,"order_description":"Dsadas","reason_for_cancellation":null,"order_type":"delivery","vat":0,"delivery_fee":0,"total":200,"rider_rating":null,"customer_rating":null,"restaurant_rating":null,"service_rating":null,"reviews":null,"created_at":"2019-11-29 12:38:11","order_status":{"id":5,"title_en":"Accepted By Restaurant","title_restaurant":"In progress","title_rider":"New","title_customer":"In progress","slug":"accepted_by_restaurant","active":1}}}

它是有效的 json 我检查了验证器。

但它在 swift 转换中变得无效 json：下面是代码：

if (JSONSerialization.isValidJSONObject(dataR!)){
   let jsonResponse = try JSONSerialization.data(withJSONObject: dataR!, options: .prettyPrinted)
   if let response = jsonResponse as? [String: Any]{

尝试使用此方法从 json 对象获取字典。

    func getDictionaryFromJsonString(dictString:String)-> [String: Any] {
        do {
            return try  JSONSerialization.jsonObject(with: 
            dictString.data(using: 
            String.Encoding.utf8, allowLossyConversion: true)!, options:  
             JSONSerialization.ReadingOptions.allowFragments) as! Dictionary
        } catch {
            return [:]
        }
    }
