ios - 如何在查询中组合 2 个 json

Question

我需要附加 2 个 JSON。
目前它正在打印为两个单独的 Json。
我如何结合我的阅读？？？？我希望我的 Json 将两个读数放在一起。

let query = HKSampleQuery(sampleType: glucoseType!, predicate: predicate, limit: 5, sortDescriptors: nil) { (query, results, error) in
                for result in results as! [HKQuantitySample] {
                  let bloodGlucose = result.quantity.description
                  let bloodGlucoseItem = HealthDataItem(endDate: result.endDate, value: String(bloodGlucose), startDate: result.endDate, type: .bloodGlucose)
                          let healthData = [bloodGlucoseItem]
                          do {
                            let data = try JSONEncoder().encode(healthData)
                            let json = String(data: data, encoding: String.Encoding.utf8)
                            for i in 0..<results!.count {
                              if (i != 0){
                                json!.append(json!)
                              }
                              print("json data:", json as Any )
                            }
                            resolve(json)
                          } catch {
                               //error handling
                          }
                }
            }

安慰：

json data: Optional("[{\"value\":\"8 mg\\/dL\",\"endDate\":635390040,\"startDate\":635390040,\"type\":\"bloodGlucose\"}]")
