QuickLookCodeSnippet
A QuickLook generator for Xcode’s .codesnippet files.
Status
Does not work: the generator does not seem to successfully register with the system. It used to work, but presumably some change in OS X broke it. The Info.plist seems to be similar to those of other QuickLook generators.
Installation
Open the Xcode project, build, then move the produced qlgenerator bundle into ~/Library/QuickLook/.
