title: Git ignore file for Xcode 4 projects
body: <p>Which files are better to ignore in git for an Xcode 4(.3.2)? This older <a href="https://stackoverflow.com/questions/49478/git-ignore-file-for-xcode-projects">question</a> addresses the same issue but I find my structure to be different so I assume it's about an older version of Xcode.</p>
