How do I parse XML web service in Swift?

Question

I don't know how to parse in my below code.. Can someone

func callService(usr: String, pwdCode: String) {

    let url = NSURL(string: "http://inspect.dev.cbre.eu/SyncServices/api/jobmanagement/PlusContactAuthenticationPost")
    var xmlParse:NSString  = ""
    var data : NSData!
    let request = NSMutableURLRequest(URL: url!)
    request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
     request.HTTPMethod = "POST"
    let dictionary = ["email": usr, "userPwd": pwdCode]
    var error: NSError?
    if let body = NSJSONSerialization.dataWithJSONObject(dictionary, options: nil, error: &error) {
        request.HTTPBody = body
    } else {
        println("JSON error: \(error)")
    }

    let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
        (data, response, error) in
        println(NSString(data: data, encoding: NSUTF8StringEncoding))

        // xmlParse=NSString(data: data, encoding: NSUTF8StringEncoding)!
        // let data = (xmlParse as NSString).dataUsingEncoding(NSUTF8StringEncoding)
        // NSXMLParser(data : NSData)

        // xmlParse=NSString(data: data, encoding: NSUTF8StringEncoding)!
        // xmlParse=response
        // println(xmlParse)
    }
    task.resume()

}

For anyone still looking, here is the code I used that worked quite well to convert the xml response into Dictionaries/Arrays, thanks to the SWXMLHash class...

UPDATED SWIFT 2.0

    let baseUrl = "http://www.example.com/file.xml"
    let request = NSMutableURLRequest(URL: NSURL(string: baseUrl)!)
    let session = NSURLSession.sharedSession()
    request.HTTPMethod = "GET"

    var err: NSError?

    let task = session.dataTaskWithRequest(request) {
        (data, response, error) in

        if data == nil {
            print("dataTaskWithRequest error: \(error)")
            return
        }

        let xml = SWXMLHash.parse(data)

        if let definition = xml["entry_list"]["entry"][0]["def"].element?.text {
            // ...
        }

        dispatch_async(dispatch_get_main_queue(),{
            // use main thread for UI updates
        })

    }
    task.resume()
