Here's how to download any files and save to Photos(if image file) or Files (if pdf)
let urlString = "your file url"
let url = URL(string: urlString)
let fileName = String((url!.lastPathComponent)) as NSString
// Create destination URL
let documentsUrl:URL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first as URL!
let destinationFileUrl = documentsUrl.appendingPathComponent("\(fileName)")
//Create URL to the source file you want to download
let fileURL = URL(string: urlString)
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 {
// Success
if let statusCode = (response as? HTTPURLResponse)?.statusCode {
print("Successfully downloaded. Status code: \(statusCode)")
}
do {
try FileManager.default.copyItem(at: tempLocalUrl, to: destinationFileUrl)
do {
//Show UIActivityViewController to save the downloaded file
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()
