Download multiple URLs using Alamofire 5 - ios

Question

I want to download the file from the URL Array and put the results stored in another Array.
Ex.
let urls = [URL1,URL2,URL3,....]
for url in urls {
AF.download(url, method: .get, parameters: nil, encoding: URLEncoding.default, headers:
headers, interceptor: nil, to: destination).response { (responseData) in
self.urlLoad.append(responseData.fileURL!)
completion(self.urlLoad)
}
}
What I am having a problem with right now is the download and get the same result. I don't know what to do. Please guide me

You haven’t shared your destination, but the question is how that closure was defined and how you built the URL that was returned. But you want to give it a DownloadRequest.Destination closure that returns a unique path for each URL. For example, you can tell it to put the downloads in the “caches” folder like so:
let urls = [
"https://spaceflight.nasa.gov/gallery/images/apollo/apollo17/hires/s72-55482.jpg",
"https://spaceflight.nasa.gov/gallery/images/apollo/apollo10/hires/as10-34-5162.jpg",
"https://spaceflight.nasa.gov/gallery/images/apollo-soyuz/apollo-soyuz/hires/s75-33375.jpg",
"https://spaceflight.nasa.gov/gallery/images/apollo/apollo17/hires/as17-134-20380.jpg",
"https://spaceflight.nasa.gov/gallery/images/apollo/apollo17/hires/as17-140-21497.jpg",
"https://spaceflight.nasa.gov/gallery/images/apollo/apollo17/hires/as17-148-22727.jpg"
].compactMap { URL(string: $0) }
let folder = try! FileManager.default
.url(for: .cachesDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
.appendingPathComponent("images")
for url in urls {
let destination: DownloadRequest.Destination = { _, _ in
let fileURL = folder.appendingPathComponent(url.lastPathComponent)
return (fileURL, [.removePreviousFile, .createIntermediateDirectories])
}
AF.download(url, to: destination).response { responseData in
switch responseData.result {
case .success(let url):
guard let url = url else { return }
self.urlLoad.append(url)
case .failure(let error):
print(error)
}
}
}
Or, alternatively:
for url in urls {
AF.download(url) { _, _ in
(folder.appendingPathComponent(url.lastPathComponent), [.removePreviousFile, .createIntermediateDirectories])
}.response { responseData in
switch responseData.result {
case .success(let url):
guard let url = url else { return }
self.urlLoad.append(url)
case .failure(let error):
print(error)
}
}
}
