Code for uploading the image:

class func uploadImage(url:String, param:[String:AnyObject], image:UIImage, completionHandler: @escaping CompletionHandlerType){
    let imageData: Data = UIImagePNGRepresentation(image)!
    Alamofire.upload(multipartFormData:{ multipartFormData in
        multipartFormData.append(imageData, withName: "image",fileName: "image.png", mimeType: "image/png")
        for (key, value) in param {
            multipartFormData.append(value.data(using: String.Encoding.utf8.rawValue)!, withName: key)
        }
    },
         to:url,
         method:.put,
         headers:getHeader(),
         encodingCompletion: { encodingResult in
            switch encodingResult {
            case .success(let upload, _, _):
                upload.responseJSON { response in
                    debugPrint(response)
                    completionHandler(.Success(true))
                }
            case .failure(let encodingError):
                print(encodingError)
            }
    })
}

I am adding the parameter as following:

    if !name.isEmpty{
        parameters["name"] = name as AnyObject
    }
    if !email.isEmpty{
        parameters["email"] = email as AnyObject
    }
    if !password.isEmpty{
        parameters["password"] = password as AnyObject
    }
    if !mobile.isEmpty{
        parameters["mobile"] = mobile as AnyObject
    }

I think you getting response in true or false that is 1 or 0 that is your problem — vp2698

Your problem is here

  multipartFormData.append(value.data(using: String.Encoding.utf8.rawValue)!, withName: key)
    }

as the

  param:[String:AnyObject]

contains a value of type NSNumber , so you can try convert NSnumber to string

   let myString = value.stringValue
   let myData = myString.data(using: .utf8)

Edit

  var parameters:[String:String]?

///

  if !name.isEmpty{
        parameters["name"] = name as String
    }
    if !email.isEmpty{
        parameters["email"] = email as String
    }
    if !password.isEmpty{
        parameters["password"] = password as String
    }
    if !mobile.isEmpty{
        parameters["mobile"] = mobile as String
    }


  parameters["userid"] = String(userid)
