如何将Alamofire与AEXML或SWXMLHASH结合使用

Question

I want to parse a XML from URL which is RSS of my blog with SWXMLHASH or AEXML libraries. I found a solution for this but when I tried the solution my app crashed. It is the encountered problem: fatal error: unexpectedly found nil while unwrapping an Optional value (lldb)

And there are my codes which are in viewDidLoad:

` Alamofire.request("http://myblog.com/feed").responseJSON { response in

        if let data = response.data {

        let xml = SWXMLHash.parse(data)
           let news = xml["rss"]["channel"]["item"][0]["title"].element?.text
           print(news!)
        }
        }
`

Is there any other solution for this? I don't want to use NSXMLParser, I want to use these kind of libraries or If it is exist any up-to-date library, I can use.

Thank you for your help!

Use

Alamofire.request("http://myblog.com/feed").response

not Alamofire.request("http://myblog.com/feed").responseJSON

I used AEXML.. try this

Alamofire.request("http://myblog.com/feed").response { res in

        guard let xml = res.data else {
            return
        }

        var options = AEXMLOptions()
        options.parserSettings.shouldProcessNamespaces = false
        options.parserSettings.shouldReportNamespacePrefixes = false
        options.parserSettings.shouldResolveExternalEntities = false

        do {
            let xmlDoc = try AEXMLDocument(xml: xml, options: options)

            print(xmlDoc.root["channel"]["item"]["title"].value!)

        } catch let error {
            print(error)
        }
}
