Consuming SOAP web service with Swift

I am expecting XML SOAP response from w3schools.com example ( http://wwww.w3schools.com/webservices/tempconvert.asmx ), but what I get is a pure html urlString. I am following the example from http://webindream.com/soap-with-swift/

thanks for the help

import UIKit

class ViewController: UIViewController, UITextFieldDelegate, NSURLConnectionDelegate, NSXMLParserDelegate {

    var mutableData: NSMutableData = NSMutableData.alloc()
    var currentElementName: NSString = ""

    @IBOutlet weak var txtCelsius: UITextField!
    @IBOutlet weak var txtFahrenheit: UITextField!

    @IBAction func btnConvert(sender: AnyObject) {

        var celsius = txtCelsius.text

        var soapMessage = "<?xml version='1.0' encoding='utf-8'?><soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'><soap:Body><CelsiusToFahrenheit xmlns='http://www.w3schools.com/webservices/'><Celsius>\(celsius)</Celsius></CelsiusToFahrenheit></soap:Body></soap:Envelope>"
        var urlString = "http://wwww.w3schools.com/webservices/tempconvert.asmx"
        var url = NSURL(string: urlString)
        var theRequest = NSMutableURLRequest(URL: url!)
        var msgLength = String(countElements(soapMessage))

        theRequest.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
        theRequest.addValue(msgLength, forHTTPHeaderField: "Content-Length")
        theRequest.addValue("http://www.w3schools.com/webservices/CelsiusToFahrenheit", forHTTPHeaderField: "SOAPAction")
        theRequest.HTTPMethod = "POST"
        theRequest.HTTPBody = soapMessage.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)

        var connection = NSURLConnection(request: theRequest, delegate: self, startImmediately: true)
        connection?.start()

        if(connection == true) {
            var mutableData : Void = NSMutableData.initialize()
        }

    }

    func connection(connection: NSURLConnection!, didReceiveResponse response: NSURLResponse!) {
        mutableData.length = 0
    }

    func connection(connect: NSURLConnection!, didReceiveData data: NSData!) {
        mutableData.appendData(data)
    }

    func connectionDidFinishLoading(connection: NSURLConnection!) {
        var xmlParser = NSXMLParser(data: mutableData)
        xmlParser.delegate = self
        xmlParser.parse()
        xmlParser.shouldResolveExternalEntities = true
    }

    func parser(parser: NSXMLParser!, didStartElement elementName: String!, namespaceURI: String!, qualifiedName qName: String!, attributes attributeDict: NSDictionary!) {
        currentElementName = elementName
    }

    func parser(parser: NSXMLParser!, foundCharacters string: String!) {
        println(string)
        if currentElementName == "CelsiusToFahrenheitResult" {
            txtFahrenheit.text = string
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        println("View did Load")
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}

All you have to do is add? wsdl at the end of the url http://www.w3schools.com/webservices/tempconvert.asmx?wsdl



PS: You can also create Swift Soap Client for this WSDL at: http://wsdl2swift.com (Disclaimer: I'm the author)
