Upload form-data with SwiftUI and Express backend - swift

Question

I want to upload some user data for register new users and I want to upload a profile picture. I'v tried with this code but it doesn't work, on my backend im just receiving a request with nothing like a form-data inside.
This is my swift code
func UserRegisterRequest(firstname: String, lastname: String, username: String, email: String, password: String, image: UIImage , completionHandler: #escaping (ReturnMessage) -> Void) {
let parameters = ["name": "MyTestFile123321",
"id": "12345"]
// MARK: URL Components
var components = URLComponents()
components.scheme = "https"
components.host = "my-url"
components.path = "/register"
//MARK: Create URL
guard let url = components.url else {
print("Invalid URL")
return
}
guard let mediaImage = Media(withImage: image, forKey: "profilePicture") else { return }
var request = URLRequest(url: url)
request.httpMethod = "POST"
//create boundary
let boundary = generateBoundary()
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
//call createDataBody method
let dataBody = createDataBody(withParameters: parameters, media: [mediaImage], boundary: boundary)
request.httpBody = dataBody as Data
print(request.httpBody)
URLSession.shared.dataTask(with: request) {
data, response, error in
if let data = data {
do {
let decoder = JSONDecoder()
decoder.dateDecodingStrategy = .formatted(DateFormatter.customFormatter)
let response = try decoder.decode(ReturnMessage.self, from: data)
completionHandler(response)
}catch(let error) {
print(error.localizedDescription)
}
} else {
print("No Data")
}
}.resume()
}
func generateBoundary() -> String {
return "Boundary-\(NSUUID().uuidString)"
}
func createDataBody(withParameters params: Parameters?, media: [Media]?, boundary: String) -> Data {
let lineBreak = "\r\n"
var body = Data()
if let parameters = params {
for (key, value) in parameters {
body.append("--\(boundary + lineBreak)")
body.append("Content-Disposition: form-data; name=\"\(key)\"\(lineBreak + lineBreak)")
body.append("\(value + lineBreak)")
}
}
if let media = media {
for photo in media {
print(photo)
body.append("--\(boundary + lineBreak)")
body.append("Content-Disposition: form-data; name=\"\(photo.key)\"; filename=\"\(photo.filename)\"\(lineBreak)")
body.append("Content-Type: \(photo.mimeType + lineBreak + lineBreak)")
body.append(photo.data)
body.append(lineBreak)
}
}
body.append("--\(boundary)--\(lineBreak)")
return body
}
I don't know if this is the right way to do it but any help is welcome.
thanks for you helping me guys
