If your value is Any type then check this may be it helps you.

for (key, value) in params {
  let paramsData:Data = NSKeyedArchiver.archivedData(withRootObject: value)
  formData.append(paramsData, withName: key)
}

Rough solution:
If you insist on put Image data into a dictionary, you could convert image data to Base64 code, and then put Base64 string in the dictionary. You will submit a big JSON to the server. I don't think it's a good solution.

Better solution:
Another WebApi to submit images data, and that API will return uploaded images URL like https://www.example.com/image1234.jpg, or just return image id like "1234" which can be embedded to a URL lately. Finally, you submit the JSON data with image URL or id like {"image":"https://www.example.com/image1234.jpg"} or {"image":1234}.

No i don't want to put image inside Dictionary – Dhiru Jun 04 '19 at 08:14 — Dhiru, Jun 04 '19 at 08:14
