I’ve been looking for a new color scheme for Vim and XCode for some time. In Apple’s defense the XCode default theme is pretty good, but after several hours of programming the light colors can get a little straining on the eyes, so I experimented with a number of the included darker themes. They’re pretty nice, but none of them was really doing it for me, so I started googling for alternatives and quickly found a few that I liked. The process for installing a new theme in XCode is not as straightforward as one might expect from an Apple application. This step by step guide should help you install your own or other custom XCode themes.
Open open your terminal and enter the following command cd library/developer/xcode/userdata/fontandcolorthemes. If you get an error that there is now such file or directory change the command to use rmkdir instead of cd, so it would be this instead: mkdir library/developer/xcode/userdata/fontandcolorthemes.
Now all that you have to do is google around until you find a theme that you like and copy it into that directoy; you can copy it any way you like, so either using the cp command via the terminal or graphically via Finder. Hope that this helps, if you have a comment or question please leave it in the comments.
