如何修復 swift 中成功和失敗案例的 Alamofire 5 錯誤？

Question

在我的項目中，我使用的是 Alamofire 5.9.3，以下是將數據上傳到服務器。

    APISessionController.sharedInstance.sessionManager().upload(multipartFormData: { (multipartFormData) in
            
            for (key, value) in parameters {
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
            }
        }, to:url)
        { (result) in
            switch result {
                
            case .success(let upload, _, _): // Getting Error: '_' can only appear in a pattern or on the left side of an assignment
                upload.uploadProgress(closure: { (Progress) in
                        self.delegate.uploadProgress(Progress.fractionCompleted)
                })
                
                upload.responseJSON { response in
                    if let JSON = response.result.value as? Dictionary<String, AnyObject> {
}

            case .failure(_): //Getting Error : '_' can only appear in a pattern or on the left side of an assignment

Previoulsy 我使用的是 Alamofire 4.9.1，它工作正常。 但它在 Alamofire 5 中顯示錯誤？

Alamofire 的分段上傳 API 在 Alamofire 5 中發生了變化。不再需要編碼完成閉包，您可以使用普通的 Alamofire API。

APISessionController.sharedInstance.sessionManager().upload(multipartFormData: { (multipartFormData) in
            
            for (key, value) in parameters {
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
            }
        }, to:url)
  .uploadProgress { }
  .response { }
