Call this function only pass url and after downloading it will be return file url........
func get_file(httpUrl:String)
{
let documentsUrl = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
let url = URL(string: httpUrl)!
let destinationUrl = documentsUrl.appendingPathComponent(url.lastPathComponent)
let session = URLSession(configuration: URLSessionConfiguration.default, delegate: nil, delegateQueue: nil)
var request = URLRequest(url: url)
request.httpMethod = "GET"
let task = session.dataTask(with: request, completionHandler:
{
data, response, error in
if error == nil
{
if let response = response as? HTTPURLResponse
{
if response.statusCode == 200
{
if let data = data
{
if let _ = try? data.write(to: destinationUrl, options: Data.WritingOptions.atomic)
{
print(destinationUrl.absoluteString)
}
else
{
print(error!)
}
}
else
{
print(error!)
}
}
}
}
else
{
print(error!)
}
})
task.resume()
}
here you caught your file ..
let documentsUrl = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
let url = URL(string: file_str)!
let destinationUrl = documentsUrl.appendingPathComponent(url.lastPathComponent)
