How to highlight lines in Xcode that have been changed

Question

Is there a way to get Xcode to highlight or mark the lines in a file that have been changed? Something like what it does for search results or warnings and errors would be great.

Answer 1

Click on "Show the version editor" in the toolbar of Xcode. This will show you a side by side view of your current version of the file compared to the file as it was with your previous commit (I am assuming you are using git).
