iOS : How to upload multiple images to server using multipart using alamofire - ios

Question

I have to upload multiple images to the server through alamofire. I am able to get the images in the form of array, convert them to data but when i upload them to the server only first image is appearing.
I am sharing my code please help.
i am getting image array of this type
image array== [<UIImage:0x2804cb210 anonymous {1170, 2532}
renderingMode=automatic(original)>, <UIImage:0x2804f03f0 anonymous
{1170, 2532} renderingMode=automatic(original)>]
and when i convert it to data from the code i got this response
print("image array==", self.images)
self.photoImageData = self.images.compactMap { $0.pngData() }
print("====", photoImageData)
==== [4074684 bytes, 1353198 bytes]
here is my function
func hitPostAPIWithprofileImageArray(urlString: String, params: [String: String],imageData: [Data],imageKey: String, completionHandler:#escaping (_ result: [String: Any], _ errorC : Error?) -> Void)
{
print("params-> ",params)
let openUrl : URL
openUrl = URL(string: baseURL + urlString)!
print("params-> ",openUrl)
Alamofire.upload(
multipartFormData: { multipartFormData in
for imageData in imageData {
multipartFormData.append(imageData, withName: imageKey, fileName: "user.jpg", mimeType: "image/jpeg")
}
for (key, value) in params {
multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
}
},
to: openUrl,
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
debugPrint(response)
do{
let result = try JSONSerialization.jsonObject(with: response.data!, options: JSONSerialization.ReadingOptions.allowFragments) as! [String:Any]
print(result)
let errorC = Error.self
completionHandler(result,errorC as? Error)
}catch{
if let err = response.error {
completionHandler(self.resultG,err as? Error); return
}
} }
upload.uploadProgress(queue: DispatchQueue(label: "uploadQueue"), closure: { (progress) in
})
case .failure(let encodingError):
print(encodingError)
completionHandler(self.resultG,encodingError as? Error)
}
}
)
}
