The result come like this start with XML, Can I remove the XML part using code, thanks for helping it is been 4 weeks now I couldn't find a similar case online

This is not json response. It xml reponse. You can't parse this by json serialization.
You need a XML parser to parse this response. For more see this tutorial.
 
    
    Actually XML format in the response supersedes JSON, so you will need to parse first XML (NSXMLParser, RaptureXML, AFXMLParserResponseSerializer) and then the object you obtain will be JSON string which you need.
 
    
    try this XML/HTML parser: Fuzi
import Fuzi
Alamofire.request(.GET, url)
    .responseString { response in
        do {
            let doc = try XMLDocument(string: response.result.value)
            if let root = doc.root {
                 // this should be the content within the <string></string> element
                print(root.stringValue)
            }
        } catch let error {
            print(error)
        }
    }
