Pattern cannot ma

Answer 1

Error is related to a small mistake(i.e .success syntax according to Alomofire, and change AF as Alamofire), I have correct the Syntax as well as code. Now you can use as follows:-

func postImageRequestWithURL(withUrl strURL: String,withParam postParam: Dictionary,withImages imageArray:NSMutableArray,completion:@escaping (_ isSuccess: Bool, _ response:NSDictionary) -> Void) {

          Alamofire.upload(multipartFormData: { (MultipartFormData) in
          // Here is your Image Array
          for (imageDic) in imageArray {
              let imageDic = imageDic as! NSDictionary
              for (key,valus) in imageDic {
                  MultipartFormData.append(valus as! Data, withName:key as! String,fileName: "file.jpg", mimeType: "image/jpg")
              }
          }

          for (key, value) in postParam {
              MultipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
          }
          }, usingThreshold: UInt64.init(), to: strURL, method: .post, headers:["userId":"mfjeriefei","key":"cnhsdnchsj"]) {(result) in
          switch result {
          case .success(let upload, _, _): //........here getting error
              upload.uploadProgress(closure: {(progress) in
                  print("Upload Progress: \(progress.fractionCompleted)")
              })
              upload.responseJSON { response in
                  if response.response?.statusCode == 200 {
                      let json = response.result.value as? NSDictionary
                      completion(true,json!);
                  }
                  else {
                      let json = response.result.value as? NSDictionary
                      completion(false,json!);
                  }
              }
          case .failure(let encodingError)://............here getting error
              print(encodingError)
              completion(false,[:]);
          }
      }
  }
