How do I show downloaded videos in iOS Storage settings - ios

Question

I've created a streaming video app that also downloads videos locally. How can I display downloaded videos in the iPhone/iPad Storage sections of settings?
I'm downloading using background tasks, and on complete running
let docsUrl = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
let destinationUrl = docsUrl.appendingPathComponent(videoId + ".mp4")
let fileManager = FileManager.default
try? fileManager.removeItem(at: destinationUrl)
do {
try fileManager.copyItem(at: location, to: destinationUrl)
} catch let error {
print("Could not copy file to disk: \(error.localizedDescription)")
return
}
Apps like Netflix, Disney+ and Prime Video all show the downloaded shows and allow them to be deleted individually, but I haven't been able to figure out how it's done. All searches usually lead to guides for users on how to delete videos.
Anybody have any tips?

This code is working for me:
func downloadVideo1(videoString :String)
{
let myStringArr = videoString.components(separatedBy: "/")
let finalString = myStringArr[myStringArr.count - 1]
let session = URLSession(configuration: URLSessionConfiguration.default, delegate: self, delegateQueue: OperationQueue.main)
let docsUrl = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
let destinationUrl = docsUrl.appendingPathComponent(finalString)
if(FileManager().fileExists(atPath: destinationUrl.path)){
print("\n\nfile already exists\n\n")
}
else{
// setupProgress()
//DispatchQueue.global(qos: .background).async {
var request = URLRequest(url: URL(string: videoString)!)
request.httpMethod = "GET"
_ = session.dataTask(with: request, completionHandler: { (data, response, error) in
if(error != nil){
print("\n\nsome error occured\n\n")
return
}
if let response = response as? HTTPURLResponse{
if response.statusCode == 200{
DispatchQueue.main.async {
if let data = data{
if let _ = try? data.write(to: destinationUrl, options: Data.WritingOptions.atomic){
print("\n\nurl data written\n\n")
print(destinationUrl)
self.checkCount = self.checkCount + 1
if self.checkCount == self.availableMediaCount
{
self.progressView.isHidden = true
let vc = TeacherLessonPlanSB.instantiateViewController(withIdentifier: "DownloadLessonVC") as! DownloadLessonViewController
self.navigationController?.pushViewController(vc, animated: true)
}
}
else{
print("\n\nerror again\n\n")
}
}//end if let data
}//end dispatch main
}//end if let response.status
}
}).resume()
}
}
