Swift Alamofire send XML request and receive XML response

问题

Hi i'm making a move from Objective C to swift. I'm trying to send xml request and receive xml response. How we can do that with Alamofire. Seem only can do for JSON?

my end point: "https://prdesb1.singpost.com/ma/GetItemTrackingDetails"

my sample request body (xml) :

<ItemTrackingDetailsRequest xmlns="http://singpost.com/paw/ns">
<ItemTrackingNumbers>
<TrackingNumber>SMT0000000628</TrackingNumber>
</ItemTrackingNumbers>
</ItemTrackingDetailsRequest>

The response should be

<ItemTrackingDetailsResponse xmlns="http://singpost.com/paw/ns" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
    <ItemsTrackingDetailList>
        <ItemTrackingDetail>
            <TrackingNumber>SMT0000000628</TrackingNumber>
            <TrackingNumberFound>true</TrackingNumberFound>
            <AlternativeTrackingNumber/>
            <TrackingNumberActive>true</TrackingNumberActive>
            <PostingDate/>
            <InsuredValue/>
            <InsuredSDR/>
            <Weight/>
            <ExpressInd/>
            <ItemCategory/>
            <Content/>

    </ItemsTrackingDetailList>
    <Status>
        <ErrorCode>0</ErrorCode>
        <ErrorDesc>Success</ErrorDesc>
    </Status>
</ItemTrackingDetailsResponse>

Seem there is no default method to deal with XML body data. Any help is much appreciate. Thanks!

update: I have tried to use Almofire but still cannot get the correct response (got nil for parsed response). My server support SSLv3 and TLS 1.0 (have already enable transport securty)

typealias CompletionHandler = (NSError?)->Void

func fetchXML(url: String, trackingNumber: String, completion: CompletionHandler) -> Void {

let params = "<ItemTrackingDetailsRequest xmlns=\"http://singpost.com/paw/ns\"><ItemTrackingNumbers><TrackingNumber>\(trackingNumber.uppercaseString)</TrackingNumber></ItemTrackingNumbers></ItemTrackingDetailsRequest>"

    let xmlRequest = NSMutableURLRequest(URL: NSURL(string: url)!)        
    xmlRequest.HTTPBody = params.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
    xmlRequest.HTTPMethod = "POST"
    xmlRequest.addValue("application/xml", forHTTPHeaderField: "Content-Type")

    Alamofire.request(xmlRequest)
             .response { request, response, data, error in

                print("url\(request?.URL?.absoluteString)")
                print("requestBody\(request?.HTTPBody)")
                print(params)

                print("error\(error.debugDescription)")
                print("status code\(response?.statusCode)")
                let xml = XML.parse(data!)
                print(xml.text)

            }
}

and call from viewcontroller

let trackingItemUrl = "https://prdesb1.singpost.com/ma/GetItemTrackingDetails"

    self.networking.fetchXML(trackingItemUrl, trackingNumber: "SMT0000000628") { error in
        print("can we get here?")
    }
