Introduction

The Interface Builder Kit is a framework containing the classes you use to implement custom plug-ins for Interface Builder. A plug-in injects one or more custom objects into Interface Builder’s library window. From the library window, users can access your custom objects and drag them into their nib files just as they would the standard system controls. You can also use this framework to implement inspectors for manipulating your objects at runtime.

The Interface Builder Kit is part of Xcode and as such is installed with the other developer tools in your Xcode installation directory and not in the /System/Library/Frameworks directory. The default installation for Xcode is the /Developer directory.
