How can I add Core Animation framework to my Xcode project?

I just can't find that framework for adding it. Any ideas?

From stackoverflow

• Add the QuartzCore framework. It contains CoreAnimation.

• You need to add the QuartzCore framework to your project.

• Also, make sure that you do an

  #import <QuartzCore/QuartzCore.h>
  

  before using any Core-Animation-specific classes, etc.
