Apple Publishes Six Free Electronic Books for Developers!

Apple’s passing out Christmas gifts early for Mac and iOS developers. The company is offering six development books covering Mac OS X and iOS development — for free.

The new eBooks aren’t really new, but they haven’t been available in the iBookstore until today. Previously developers could either read them online or download PDF versions to read later via developer.apple.com.
The six titles include: Cocoa Fundamental’s Guide, The Objective-C Programming Language, iOS Application Programming Guide, Object Oriented Programming With Objective-C, iOS Technology Overview, and iOS Human Interface Guidelines.
