May this GitHub code will help you.

protocol SwiftJsonMappable {
   func getDictionary() -> [String: Any]
   func JSONString() -> String
}



extension SwiftJsonMappable {

//Convert the Swift dictionary to JSON String
func JSONString()  -> String {
    do {
        let jsonData = try JSONSerialization.data(withJSONObject: self.getDictionary(), options: .prettyPrinted)
        // here "jsonData" is the dictionary encoded in JSON data

        let jsonString = String(data: jsonData, encoding: .utf8) ?? ""
        // here "decoded" is of type `Any`, decoded from JSON data
        return jsonString
        // you can now cast it with the right type

    } catch {
        print(error.localizedDescription)
    }
    return ""

}

//Convert Swift object to Swift Dictionary

            if !checkAnyContainsNil(object: child.value) {

                //Check whether is custom swift class
                if isCustomType(object: child.value) {
