Handling XML data with Alamofire in Swift

Alamofire 4.x - Swift 3.x:

(please note that in this example I've used URLEncoding.default instead of URLEncoding.xml because the xml parameter exclude the possibility to pass parameters and headers, so default is more confortable.)

let url = "https://httpbin.org/get"
let parameters: Parameters = ["foo": "bar"]
let headers: HTTPHeaders = [
    "Authorization": "Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==",
    "Accept": "application/json"
]
Alamofire.request(url, method: .get, parameters: parameters, encoding: URLEncoding.default, headers: headers)
.responseString { response in
    print(" - API url: \(String(describing: response.request!))")   // original url request
    var statusCode = response.response?.statusCode

    switch response.result {
    case .success:
        print("status code is: \(String(describing: statusCode))")
        if let string = response.result.value {
            print("XML: \(string)")
        }
    case .failure(let error):
        statusCode = error._code // statusCode private
        print("status code is: \(String(describing: statusCode))")
        print(error)
    }
}

Alamofire 3.0 october 2015 and Xcode 7 according to the 3.0.0-beta.3 README and the Alamofire 3.0 Migration Guide.

For me the correct syntax is:

Alamofire.request(.GET, url, parameters: params, encoding: ParameterEncoding.URL).responsePropertyList { response in

            if let error = response.result.error {
                print("Error: \(error)")

                // parsing the data to an array
            } else if let array = response.result.value as? [[String: String]] {

                if array.isEmpty {
                    print("No data")

                } else { 
                    //Do whatever you want to do with the array here
                }
            }
        }

If you want a good XML parser, please take a look to SWXMLHash.

An example could be: let xml = SWXMLHash.parse(string)

If I did not misunderstand your description, I think you would like to get the XML data and parse it, right? Regarding to this, you may handle with wrong variables in the response callback. You should println(data) to check the XML document.

For parsing XML data, you could consider SWXMLHash. The Alamofire request could look like:

Alamofire.request(.GET, "http://my-web-service-domain.com", parameters: nil)
         .response { (request, response, data, error) in
            println(data) // if you want to check XML data in debug window.
            var xml = SWXMLHash.parse(data!)
            println(xml["UserDTO"]["FilmID"].element?.text) // output the FilmID element.
         }
