for JPEG image on network use
let imageData = UIImageJPEGRepresentation(img, 0.5) and at body
multipartFormData.append(dataImg, withName: "shopImage", fileName: "uploaded_file.jpeg", mimeType: "image/jpeg").
for PNG image
let image = UIImagePNGRepresentation(pickedImage) and at body
multipartFormData.append(dataImg, withName: "shopImage", fileName: "uploaded_file.png", mimeType: "image/png").
