How I can get Image from document directory if i don't know it's name

Question

I saved image with this func:

let image = categoryImage.image
        let data = image!.jpegData(compressionQuality: 0.5)!
        let name = "\(Int(Date().timeIntervalSince1970))"
        do {
            let documentDirectory = try FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor:nil, create:false)
            let fileURL = documentDirectory.appendingPathComponent(name)

            try data.write(to: fileURL)

            print(fileURL)

        } catch {
            print(error.localizedDescription)
        }

I get image from this:

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellPrototype

        // Configure the cell...
        let currentItem = item[indexPath.row]
        cell.pointNameLabel.text = currentItem

        let nsDocumentDirectory = FileManager.SearchPathDirectory.documentDirectory
        let nsUserDomainMask    = FileManager.SearchPathDomainMask.userDomainMask
        let paths               = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true)
        if let dirPath          = paths.first{
            let imageURL = URL(fileURLWithPath: dirPath).appendingPathComponent("test")
            let image    = UIImage(contentsOfFile: imageURL.path)
            cell.categoryImage.image = image
        }
        return cell
    }

When i get image back i can't take it's name which was created by (Int(Date().timeIntervalSince1970))

How I can take specifically the file name that was created

When i take image name for example "test" image pass in cell

But in my app user select image and i don't know which image user selected
