Now available in the Mac App Store

has officially released version 4 of Xcode, the integrated development environment designed to help developers write apps for Mac OS X and iOS.

Xcode 4 was rewritten completely from scratch and features a significant number of changes from its predecessor, many of which are aimed at improving the workflow that developers use to program apps on the company’s two operating systems.

In another break with tradition, however, the company has chosen to also make the IDE available to the general public through the Mac App Store, where it can be purchased for the modest sum of £2.99. Xcode 4, which is a hefty 4.24GB download, requires Mac OS X 10.6.6.
