Alamofire 4.5.1 fails after updating to iOS 11.1 - download

Question

after updating to iOS 11.1 the .sqlite download fails. I have verified that I have the Alamofire libraries up to date (4.5.1), I have uninstalled and reinstalled using pod. I have cleaned the project and tried to debug it but I can not find the problem, only i note that the temporaryURL is nil.
My code:
let parameters: Parameters = [:]
var filePath: URL?
let destination: (URL, HTTPURLResponse) -> (URL, DownloadRequest.DownloadOptions) = {
(temporaryURL, response) in
if let directoryURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first, let suggestedFilename = response.suggestedFilename {
filePath = directoryURL.appendingPathComponent("\(suggestedFilename)")
return (filePath!, [.removePreviousFile, .createIntermediateDirectories])
}
return (temporaryURL, [.removePreviousFile, .createIntermediateDirectories])
}
Alamofire.download("https://s3-eu-west-1.amazonaws.com/xxx/xxx/xxx.sqlite3", method: .get, parameters: parameters, encoding: JSONEncoding.default, to: destination)
.downloadProgress { progress in
DispatchQueue.main.async
{
/.../
}
}
.validate { request, response, temporaryURL, destinationURL in
/.../
return .success
}
.response { response in
debugPrint(response)
print("Descarga finalizada");
/.../
}
The .downloadProgress works fine. But when it reaches 100% the process does not continue and is waiting until it ends because of the waiting time exhausted (-1001)
The console Output with the debug:

Descarga finalizada
However, the file has been downloaded to the path:
I have changed the destination of the file using a simpler version like:
let destination = DownloadRequest.suggestedDownloadDestination(for: .documentDirectory)
But the problem is the same.
With iOS 10.3 works perfectly.
I appreciate any help, thx.

Answer 1

I have solved it by removing the additional parameters from:
Alamofire.download("https://s3-eu-west-1.amazonaws.com/xxx/xxx/xxx.sqlite3", method: .get, parameters: parameters, encoding: JSONEncoding.default, to: destination)
To:
Alamofire.download("https://s3-eu-west-1.amazonaws.com/xxx/xxx/xxx.sqlite3", to: destination)
I'm not sure what's wrong but that's how it works
