Json error: The data couldn’t be read because it isn’t in the correct format.

I get data from here jsonBody
How can I get a good format?
override func stompClient(client: StompClientLib!, didReceiveMessageWithJSONBody jsonBody: AnyObject?, withHeader header: [String : String]?, withDestination destination: String) {

Optional({
dateMessage = 1564591416932;
id = 3608;
idFeed = 3193;
idSender = 996;
linkPhotoAvatar = "https://s3.us-east-1.amazonaws.com/images-views/chat/1553479212385-1553479211398.jpg";
message = Test;
messageViewed = 0;
nameSender = "test3 test";
type = 0;
})

I am sorry, I found a solution such as:

let jsonData = try JSONSerialization.data(withJSONObject: jsonBody as Any, options: .prettyPrinted)
            let reqJSONStr = String(data: jsonData, encoding: .utf8)
            
            print("JSON Body : \(reqJSONStr)")
            let jsonResponse = FeedsComments.deserialize(from: reqJSONStr) as! FeedsComments
