Earlier this week I mentioned an excellent Xcode plugin that adds intelligent code coloring providing a unique color for each variable in your code.
Here a few more handy new Xcode plugins:
Adjust Font Size – A plugin submitted by Sasha Zats that allows you to use hot keys to adjust the font size in the code editor that is very nice when doing presentations.
RRConstraintsPlugin – A plugin from Rolandas Razma adding a number of features to simplify setting up a constraint based layout in interface builder.
SCXCodeSwitchExpander – An Xcode plugin from Stefan Ceriu that adds auto-completion to switch/case statements filling in missing cases.
You can find more plugins on our Xcode plugin list.
