Apple today released their second preview of Xcode 4 to developers. Xcode 4 is an entirely new version of Xcode for Mac and iOS re-built with many new features and enhancements. In Xcode 3 developers usually use Xcode to code their applications and Interface Builder to creature user-interfaces. Xcode 4 combines the two applications to make developing apps a much smoother experience.
Additionally Xcode 4 brings an updated interface that is quicker and easier to navigate through. Another major addition to Xcode 4 is “code-fixing,” and this allows Xcode to fix your code errors as you type.
Xcode 4 was initially previewed at this year’s WWDC and you can learn more about it at Apple’s developer website.
