Interface Builder

Interface Builder is a software development application for Apple's Mac OS X operating system. It is part of Xcode (formerly Project Builder), the Apple Developer Connection developer's toolset. Interface Builder allows Cocoa and Carbon developers to create interfaces for applications using a graphical user interface. The resulting interface is stored as a .nib file, short for NeXT Interface Builder, or more recently, as a .xib file.

Interface Builder is descended from the NeXTSTEP development software of the same name. A version of Interface Builder is also used in the development of OpenStep software, and a very similar tool called Gorm exists for GNUstep. On March 27, 2008, a specialized iPhone version of Interface Builder allowing interface construction for iPhone applications was released with the iPhone SDK Beta 2.

Interface Builder was intentionally developed as a separate application, to allow interaction designers to design interfaces without having to use a code-oriented IDE, but as of Xcode 4, Apple has integrated its functionality directly into Xcode.

Nib (pen)

A nib is the part of a quill, dip pen or fountain pen which comes into contact with the writing surface in order to deposit ink. Different types of nibs vary in their purpose, shape and size, as well as the material from which they are made.

History

Quill

The quill replaced the reed pen across Europe by the Early Middle Ages and remained the main writing tool of the West for nearly a thousand years until the 17th century. Quills are fashioned by cutting a nib into the end of a feather obtained from a fairly large bird, such as a goose, traditionally from its left wing. A quill has the advantage of being more durable and more flexible than a reed pen, and it can also retain ink in the hollow shaft of the feather, known as the calamus, allowing more writing time between ink dippings. The quill was in common use until the early 19th century and the advent of the metal nib. For business purposes, the quill was fairly quickly overtaken; however, it remains popular for personal use and for artistic work.
