创建文件夹并在照片中保存图像/视频

Question

我已经创建了文件夹并将图像保存在该文件夹中。我希望该图像显示在照片中。我在下面编写了代码，希望图像/视频像WhatsApp一样显示。任何帮助将不胜感激。

try FileManager.default.createDirectory(atPath: newUrl!.path, withIntermediateDirectories: true, attributes: nil)
            if isSent{
                newUrl = newUrl?.appendingPathComponent("Sent")
            }else{
                newUrl = newUrl?.appendingPathComponent("Recieve")
            }
            try FileManager.default.createDirectory(atPath: newUrl!.path, withIntermediateDirectories: true, attributes: nil)
            let destinationFileUrl = newUrl?.appendingPathComponent(name)
            let fileURL = url
            let sessionConfig = URLSessionConfiguration.default
            let session = URLSession(configuration: sessionConfig)
            let request = URLRequest(url:fileURL!)
            let task = session.downloadTask(with: request) { (tempLocalUrl, response, error) in
                if let tempLocalUrl = tempLocalUrl, error == nil {
                    if let statusCode = (response as? HTTPURLResponse)?.statusCode {
                        print("Successfully downloaded. Status code: \(statusCode)")
                        DispatchQueue.main.async {
                            self.viewController?.view.makeToast("Image Downloaded")
                        }
                    }
                    FileManager.default.copyItem(at: tempLocalUrl, to: destinationFileUrl!)
                        
            }
        task.resume()
