Adding PDFKit to XCode 4.6 project

Question

I like to add the PDFKit framework to one on my OS X Cocoa projects but if I try to add it in Targets -> Summary -> Linked Frameworks and Libraries it is not there. In addition, importing it in my .h file is not successful or better to say it is not found by auto complete. What can I do?

Thanks for your help!

SOLVED! See comments!

As asked for in the comments:

Ok, obviously I had to import the Quartz framework. Now it works. Maybe this little self help here will help some others to find out :)
