This is my code. I got empty array what's wrong with my code and what is the solution for my problem.

class ImageParser: NSObject, NSXMLParserDelegate{

    var itemsStarted = false;
    var descriptionStarted  = false;
    var divStarted = false;
    var aStarted = false;
    var inImage = false;
    var images:[String] = [];

    func parser(parser: NSXMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String]) {
        if(elementName == "item"){
            itemsStarted = true;
        }

        if(itemsStarted && elementName == "description"){
            descriptionStarted = true;
        }

        if(descriptionStarted && elementName == "div"){
            divStarted = true;
        }

        if(divStarted && elementName == "a"){
            inImage = true;
        }

        if(inImage && elementName == "img"){
            images.append(attributeDict["src"]!);
        }
    }

    func parser(parser: NSXMLParser, didEndElement elementName: String, namespaceURI: String?, qualifiedName qName: String?) {
        if(elementName == "img"){
            inImage = false;
        }
    }
  }

NSXMLParser ignores anything within CDATA, so if your CDATA contains valid xml tags, what you need to do is basicly is run another instance of parser on the text inside CDATA.

this might help https://github.com/hunkier/XMLParser-Swift/blob/master/XMLParser.swift

also try adding this method to your code in swift 2:

func parser(parser: NSXMLParser!, foundCDATA CDATABlock: NSData!) {
            var datastring = String(CDATABlock: NSData!, encoding: NSUTF8StringEncoding);
}

Use NSString instead of String in earlier version of swift...syntax is the same
