无法将类型“[JSON]”的值分配给类型“[MyStruct]”

Question

我正在学习使用 SwiftyJSON，我正在尝试将结果值转换为 MyStruct 数组。但是，每当我尝试这样做时，它都会告诉我它们不兼容。如何将 [JSON] 转换为 [MyStruct]？

class TreatmentsManager: ObservableObject {

 @Published var treatments = [Treatment]()
 func testAlamofire() {
  AF.request("http://dermaservice.theappmaster.com/Tratamiento.ashx").response { response in
    switch response.result {
    case .success(let value):
        let json = JSON(value)
        if let treatmentArray = json["Tratamientos"].array {
            self.treatments = treatmentArray
         //[MyStruct] type /= [JSON] type
        }
    case .failure(let error):
        print(error)
    }}}}

感谢@VishalPatel，我找到了解决方法：

class TreatmentsManager: ObservableObject {

  @Published var treatments = [Treatment]()
  func testAlamofire() {
    AF.request("http://dermaservice.theappmaster.com/Tratamiento.ashx").response { response in
        switch response.result {
        case .success(let value):
            do {
                let results = try JSONDecoder().decode(TreatmentList.self, from: value!)
                DispatchQueue.main.async {
                  self.treatments = results.Tratamientos
                  }
                } catch {
                print(error)
                }
        case .failure(let error):
            print(error)
        }
     }
  }
}

其中 TreatmentList 是一个包含 [Treatments] 的结构。所以不需要使用 SwiftyJSON
