Apple just released an updated build of their Xcode 4 preview. Why would a person need Xcode, you ask? If you're into developing Mac or iOS applications, it's just about the only way to go. As to why a person would care about the new version of Xcode, it's a massive rewrite, featuring a rearranged application interface, fully integrated Interface Builder -- trust us, it's a huge deal -- a rewritten debugger, and even a new Fix-it feature, which not only knows what's causing the bug in your software, but can actually fix it for you. I tell you, programmers today are living in the future!
Other new features include: the Assistant, a great looking feature that helps you see the connections between the pieces of your code, and enables you to make changes to the structure of your code faster, and better; The LLVM Compiler 2.0, the next-gen, faster open source compiler, which fully supports C, Objective-C and C++; and a new Version editor that gives you Time Machine-like control over the revisions of your project.
