Download and save pdf into files from url in swift - ios

Question

I am downloading pdf from url and saving to .documentsDirectory. but it's saving somewhere inside app data, instead I want to save it on phone.
func downnload(url: NSURL, filename:String) {
let fileName = String((url.lastPathComponent!)) as NSString
let documentsUrl:URL = (FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first as URL?)!
let destinationFileUrl = documentsUrl.appendingPathComponent("\(fileName)")
let sessionConfig = URLSessionConfiguration.default
let session = URLSession(configuration: sessionConfig)
let request = URLRequest(url:url as URL)
let task = session.downloadTask(with: request) { (tempLocalUrl, response, error) in
if let tempLocalUrl = tempLocalUrl, error == nil {
// Success
if let statusCode = (response as? HTTPURLResponse)?.statusCode {
print("Successfully downloaded. Status code: \(statusCode)")
}
do {
try FileManager.default.copyItem(at: tempLocalUrl, to: destinationFileUrl)
do {
let contents = try FileManager.default.contentsOfDirectory(at: documentsUrl, includingPropertiesForKeys: nil, options: .skipsHiddenFiles)
for indexx in 0..<contents.count {
if contents[indexx].lastPathComponent == destinationFileUrl.lastPathComponent {
let activityViewController = UIActivityViewController(activityItems: [contents[indexx]], applicationActivities: nil)
self.present(activityViewController, animated: true, completion: nil)
}
}
}
catch (let err) {
print("error: \(err)")
}
} catch (let writeError) {
print("Error creating a file \(destinationFileUrl) : \(writeError)")
}
} else {
print("Error took place while downloading a file. Error description: \(error?.localizedDescription ?? "")")
}
}
task.resume()
}
}

You can save your file in to Apples' Files App using UIDocumentInteractionController
After downloading pdf from url and saving to .documentsDirectory, Give your documentsDirectory file url to UIDocumentInteractionController
let documentInteractionController = UIDocumentInteractionController()
documentInteractionController.url = url //Here is your documentsDirectory file url
documentInteractionController.uti = url.typeIdentifier ?? "public.data, public.content"
documentInteractionController.name = url.localizedName ?? url.lastPathComponent
documentInteractionController.presentOptionsMenu(from: view.frame, in: view, animated: true)
Here I'm using extension for URL
extension URL {
var typeIdentifier: String? {
return (try? resourceValues(forKeys: [.typeIdentifierKey]))?.typeIdentifier
}
var localizedName: String? {
return (try? resourceValues(forKeys: [.localizedNameKey]))?.localizedName
}
}
