Cocoa Error 3840 - NSJSONSerialization

Question

I\'m trying to parse a JSON string returned from a ASP.NET web service. The return string has been simplified to just this:

Answer 1

Is the Web service actually returning the and portions of that string within the content of the document? If so, that's the problem: The valid JSON string is simply:

[{"Firstname":"Johnny"}],

This is the only content your Web response should contain. Everything in angled brackets is not actually JSON data, and it's throwing the parser off.
