Xcode 5 - How to add Header Search Path and use GDataXMLNode

I am trying to use GDataXMLNode to parse an XML file. I am following the tutorial on this blog: http://www.raywenderlich.com/725/xml-tutorial-for-ios-how-to-read-and-write-xml-documents-with-gdataxml My problem is trying to add the GDataXMLNode to my project and getting it to work. I'm supposed to do something with the configurations, add a Header Search Path, and a few other things, but every single example I've found online is for a previous version of Xcode. I'm currently using Xcode 5 and I have tried everything (PLEASE prove me wrong), but nothing is working the way it's supposed to in this tutorial. So, any help as to how I might go about this and get it working together with my iOS project would be much appreciated. Let me know if I can expound on anything I've said.
