如何从iOS中的流中接收数据（swift）

Question

I am trying to get data from a stream in swift. I know how to handle this in Android, but I dont know what to do in iOS. In Android I do the following to read data from my server an save it as file to my device:

URL url = new URL(uri);
HttpURLConnection connection = (HttpURLConnection)url.openConnection();

connection.connect();

input = connection.getInputStream();
output = new FileOutputStream(context.getFileStreamPath(filename));

byte data[] = new byte[1024];
int count;
while ((count = input.read(data)) != -1) {
    output.write(data, 0, count);
}

File file = context.getFileStreamPath(filename);

How can I do the same with swift? I am using Alamofire for other requests.

best regards

Almofire provides methods to download streams directly. This is an example mentioned in the Almofire github page

let destination = Alamofire.Request.suggestedDownloadDestination(directory: .DocumentDirectory, domain: .UserDomainMask)
Alamofire.download(.GET, "https://httpbin.org/stream/100", destination: destination)
