Send Core Data object to post api Alamofire multipartFormData - swift

Question

I have a screen on my app that I get some fields and save on my object Order. This object is my Core Data Object. After saving it, I need to send it to my backend through Alamofire POST multipartFormData.
The problem is that this is a Core Data Object (not Codable) and I need to send Data type on multipartFormData. How can I convert my object to Data? Is there another way of doing it?
What I've done:
let order = Order(context: DatabaseController.getContext())
order.orderItem = orderItem
order.product = product
order.value = value
order.date = date
Alamofire part:
Alamofire.upload (
multipartFormData: { multipartFormData in
multipartFormData.append(order, withName: "order")
},
to: url,
headers: headers,
encodingCompletion: { encodingResult in
The problem is how to put my object Order inside multipartFormData?
Could anyone help me please?
Updated:
Ok, sending the whole object didn't work, my api didn't accept, so I made a specific json only with the fields needed and turned it a Data type:
(PS: files are Data type from images user choose, even from camera or gallery)
var files = Dictionary<Data, String>()
var jsonFiles = [[String: String]]()
var jsonOrder = [String: Any]()
for file in files {
let dict : [String: String] = [ "orderImageIdLocal": uuidOrderImageIdLocal,
"orderItemAnalysisIdLocal": uuidAnalysisIdLocal,
"urlImageLocal": "\(imageId).jpg"]
jsonFiles.append(dict)
}
jsonOrder = [ "reason": "\(textViewReason)",
"orderImagess": jsonFiles,
"orderAnalysisId": "",
"orderIdLocal": "\(uuidAnaliseIdLocal)",
"orderId": "\(orderId ?? "")",
"typeSolicitation": "\(typeSolicitation)"]
Then I convert it to Data type like you said and send to Alamofire like above:
let orderData = try? JSONSerialization.data(withJSONObject: jsonOrder, options: .prettyPrinted) {
My problem now is that my api expect a zip file with those images user took from camera or gallery. So I am trying to use ZIPFoundation. I still don't know how to zip it and send. Should I zip each picture as Data type? Then transform zip file into Data type so I can send through multipartFormData.append?
I have tried: here and here

Here the code as an extension of NSManagedObject which creates dictionary from the attributes name.
extension NSManagedObject {
func toData() -> Data? {
let keys = Array(self.entity.attributesByName.keys)
let dict = self.dictionaryWithValues(forKeys: keys)
do {
let jsonData = try JSONSerialization.data(withJSONObject: dict, options: .prettyPrinted)
return jsonData
}
catch{}
return nil
}
}
Usage:
let jsonData = order.toData()
multipartFormData.append(jsonData, withName: "order")
