try with this code
func uploadeImage(image: Data, completion: #escaping (Bool) -> Void){
alamoFireManager!.upload(multipartFormData: { (MultipartFormData) in
MultipartFormData.append(image, withName: "file", fileName: "goalImage", mimeType: "image/png")
}, usingThreshold: UInt64.init(), to: "URL FOR YOUR END POINT", method: .post, headers: headers)
{ (result) in
switch result{
case .success(let upload, _, _):
upload.responseJSON { response in
completion(true)
}
case .failure( _):
completion(false)
}
}
}
for your image try whit this function
extension UIImage{
enum JPEGQuality: CGFloat {
case lowest = 0
case low = 0.25
case medium = 0.5
case high = 0.75
case highest = 1
}
func jpeg(_ jpegQuality: JPEGQuality) -> Data? {
return jpegData(compressionQuality: jpegQuality.rawValue)
}
}
and finally, use like this code
let uploadImage = profilePicture.image.jpeg(.medium)
uploadImage(image: uploadImage){ (flag)
{
if flag
{
print("your image was uploaded")
}
}

Finally I got my mistake. I was doing image to data conversion two times. LOL
Alamofire.upload(multipartFormData: { (multipartFormData) in
for (key, value) in parameters {
if key == "file" {
multipartFormData.append(value, withName: key as String)
} else {
multipartFormData.append("\(value)".data(using: String.Encoding.utf8)!, withName: key as String)
}
}
}, usingThreshold: UInt64.init(), to: stringUrl, method: .put, headers: headers) { (result) in
switch result{
case .success(let upload, _, _):
upload.responseJSON { response in
print("Succesfully uploaded")
if let err = response.error{
onError?(err)
return
}
onCompletion?(nil)
}
case .failure(let error):
print("Error in upload: \(error.localizedDescription)")
onError?(error)
}
}
}
