        <price_options>
            <option>
                <id>622</id>
                <label>128PG Foolscap Book -3 Column-HC25511 (RED)-BK-3C1200</label>
                <price>8.90</price>
                <promo_price>0</promo_price>
                <qty>10</qty>
                <default>TRUE</default>
            </option>
        </price_options>
    </item>

And here is the code that i try to working on, but its not working, how should i save the child value? :

   func searchProducts(){

    var id = [String]()
    var price = [String]()


    let urlString = "http://dev.jocom.com.my/feed"


    Alamofire.request(.POST, urlString , parameters: ["req" : "pro_name", "code" : searchString!])

        .responseData { response in

            switch response.result {
            case .Success:

                let apiSearchXML = SWXMLHash.parse(response.data!)
                print(apiSearchXML)

                for elem in apiSearchXML["rss"]["channel"]["item"]["price_options"]["option"] {
                    id.append(elem["id"].element!.text!)
                    print("\(id)")
                }



            case .Failure(let error):
                print(error)
            }
    }


}

You need to use something else, because SWXMLHash does not support writing (as of 19 July 2016):

Does SWXMLHash support writing XML content?

No, not at the moment - SWXMLHash only supports parsing XML (via indexing, deserialization, etc.).

You can try AEXML which supports writing.
