Failed to use "getUserStreamDelimited"

[tattsun]

Hi.
I tried to use "getUserStreamDelimited", but I got an error. How to stream my user timeline?
When I used "getStatusesSampleDelimited", I got no error.

Code I tried to run:

let swifter = Swifter(consumerKey: consumerkey, consumerSecret: consumersecret, oauthToken: oauthtoken, oauthTokenSecret: oauthtokensecret)
swifter.getUserStreamDelimited(nil, stallWarnings: nil, includeMessagesFromFollowedAccounts: true, includeReplies: true, track: nil, locations: nil, stringifyFriendIDs: nil, progress: { (progress: Dictionary<String, JSONValue>?) in
            progress!.values.array.map({json in println(json)})
            }, stallWarningHandler: {
                (code: String?, mes: String?, percentFull: Int?) in
                if let warning = mes {
                    println("WARNING: ", warning)
                }
            }, failure: {(error: NSError) in
                let errmes = error.localizedDescription
                println("ERROR: ", errmes)
        })

I got an error below.

(ERROR: , HTTP Status 404: Not Found, Response: Unknown URL. See Twitter Streaming API documentation at http://dev.twitter.com/pages/streaming_api

)

Thanks.
