Uploading multiple images(with parameters) using multipart form data - Alamofire 5 - swift

Question

I have been trying to upload multiple images(3) with parameters using alamofire but i cant seem to do it.(My lack of knowledge). Could someone kindly help me out with this?
This is what i have tried
{
let headers: HTTPHeaders = [
xyz
]
let param : [String: Any] = [
"emp_Id" : "",
"device_Identifier" : "",
"timestamp" : "",
"description" : "",
"handoverStatus" : ""
]
AF.upload(
multipartFormData: { multipartFormData in
multipartFormData.append(imgData0, withName: "media1" , fileName: "file0.jpeg", mimeType: "image/jpeg")
multipartFormData.append(imgData1, withName: "media2",fileName: "file1.jpg", mimeType: "image/jpg")
multipartFormData.append(imgData2, withName: "media3",fileName: "file1.jpg", mimeType: "image/jpg")
// I think im supposed to add the last part here but i dunno how to do that
},
to: "http://ip.here.--.--/new.php", method: .post , headers: headers)
.response { resp in
print(resp)
}
}
This is what the server expects
[{"key":"media1","description":"","type":"file","value":["/C:/Users/x/x/Saved Pictures/x.jpg"]},
[{"key":"media2","description":"","type":"file","value":["/C:/Users/x/x/Saved Pictures/x.jpg"]},
[{"key":"media3","description":"","type":"file","value":["/C:/Users/x/x/x.jpg"]},
{"key":"model","value":"{\"emp_Id\": \"6\",\"device_Identifier\":\"Device 01\",\"timestamp\":\"\123\,
”\description\”:\”description\",”handoverStatus”:”false”}","type":"text"}]
I dunno how to add the last part to the multipart form data, could some point me in the right direction ?
Thanks

Try this method to upload multiple images
class func uploadImageWithURL(endPath : String, dictImage : [String:[UIImage]], parameter : [String : Any], header : HTTPHeaders? = nil, success : #escaping ( Any? )->Void, failure : #escaping (Error) -> Void){
let baseUrl = "your base URL"
let fullUrl = baseUrl + endPath
var headers = ["Content-type" : "multipart/form-data"]
if let header = header{
headers = header
}
let url = (try? URLRequest(url: fullUrl, method: .post, headers: headers))!
upload(multipartFormData: { (multipartData) in
for imagesData in dictImage {
for arrimage in imagesData.value{
multipartData.append(arrimage.jpegData(compressionQuality: 0.50)!, withName: imagesData.key, fileName: "\(Date().timeIntervalSince1970).jpg", mimeType: "image/jpeg")
}
}
for (key, value) in parameter {
multipartData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
}
}, with: url) { (resultData) in
switch resultData{
case .success(let upload, let streamingFromDisk, let fileURL):
print("File URL : \(String(describing: fileURL))")
print("Streaming From Disk : \(streamingFromDisk)")
upload.uploadProgress(closure: { (progress) in
print("Progress : \(progress.fractionCompleted)")
})
upload.responseJSON(queue: nil, options: .allowFragments, completionHandler: { (response) in
if let value = response.result.value
{
success(value)
}
})
case .failure(let error):
failure(error)
print(error)
}
}
}
