No response from URL in XML parsing using XMLMappable

Question

I am using XMLMapper with Alamofire to map a response. So far I can map most of the response, except for the Image and and Duration. Here is a link to the XML RSS Feed: https://belizing.libsyn.com/rss. Any help on how to map the duration and image? This is my data model:

struct Image: XMLMappable {
    init?(map: XMLMap) {}

    var nodeName: String!
    var image: String?

    mutating func mapping(map: XMLMap) {
        image <- map["image"]
    }


}

Answer 1

Here is an example of your XML feed:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0"
