Download PDF file and save in document directory

Question

I have the following code that allows me to download a PDF file from a URL, it works correctly:

class ViewController: UIViewController {

    @IBOutlet weak          


        

Answer 1

You need to move the file to your custom location after the download. Implement URLSessionDownloadDelegate and you will receive the location of your downloaded file.

Delegate method:

func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL)

Code to move the file:

do {
    let documentsURL = try
        FileManager.default.url(for: .documentDirectory,
                                in: .userDomainMask,
                                appropriateFor: nil,
                                create: false)

    let savedURL = documentsURL.appendingPathComponent("yourCustomName.pdf")
    try FileManager.default.moveItem(at: location, to: savedURL)
} catch {
    print ("file error: \(error)")
}
