Asihttprequest 61 errors

I'm using the ASIhttprequest in many projects but recently with each new project when I'm trying to add the ASIhttprequest classes I get the following error before using classes just when I'm trying to import them:

What is causing this?

More specifically, it requires CFNetwork, SystemConfiguration, MobileCoreServices, and lib (libz.tbd for iOS 9).

Edit: It also needs libxml2

Just to put some documentation on this

just remember to include the lixml file path in the "Header Search Paths" section of the project configuration. which is usually /usr/include/libxml2 that did the trick for me.
