由于对成员 jsonObject 的引用不明确，我无法编译我的 alamofire 代码。为什么？

Question

我在 Swift 中有一个代码，我在其中通过 Alamofire 调用我的后端代码：

Alamofire.request(url, method: .post, parameters: (parameters), encoding: JSONEncoding.default)
  .validate()
  .responseJSON { response in
      switch response.result {
      case .success:
             do {
             if let jsonData = try JSONSerialization.jsonObject(with: response.result.value, options:.allowFragments) as? [String:Any] {
              for requestJSON in jsonData["geojson"]["features"] {
                  if let request = SingleCluster.fromJSON(JSON(requestJSON)){
                      let pinOne = CustomCluster()
                      pinOne.coordinate = CLLocationCoordinate2D(latitude: request.latitude, longitude: request.longitude)
                      pinOne.amount = request.amount

                      self.eventsArray.append(pinOne);
                  }
              }
          }
             } catch let err{
              print(err.localizedDescription)
             }

          completionHandler!()

      case .failure(let error):
          print("error")
      }

}

问题是这一行：

 if let jsonData = try JSONSerialization.jsonObject(with: response.result.value, options:.allowFragments) as? [String:Any] {

出现错误：

Ambiguous reference to member 'jsonObject(with:options:)'

我试图将其转换为 [String:Any] 或 [String:AnyObject] 但它没有任何改变。我在这里做错了什么？

Answer 1

更改此行：

if let jsonData = try JSONSerialization.jsonObject(with: response.result.value, options:.allowFragments) as? [String:Any] {

收件人：

if let data = response.data, let jsonData = try JSONSerialization.jsonObject(with: data, options:.allowFragments) as? [String:Any] {

你已经使用了responseJSON和Alamofire所以你会在completion block中得到Serialized JSON，不需要使用JSONSerialization直接使用它。

switch response.result {
case .success:
     if let jsonData = JSON(response.result.value) {
         for requestJSON in jsonData["geojson"]["features"] {
              if let request = SingleCluster.fromJSON(requestJSON){
                  let pinOne = CustomCluster()
                  pinOne.coordinate = CLLocationCoordinate2D(latitude: request.latitude, longitude: request.longitude)
                  pinOne.amount = request.amount
                  self.eventsArray.append(pinOne);
              }
          }
     }
case .failure(let error):
      print("error")
}

由于对成员 jsonObject 的引用不明确，我无法编译我的 alamofire 代码。为什么？

I cannot compile my alamofire code due to ambiguous reference to member jsonObject. Why?
