Resurrecting the Library
For posterity:
- Install Lion dev preview.
- Build your plugin for [app name here].
- Notice your Library folder is missing from your home folder.
- Open Terminal.
- Type
SetFile -a v ~/Library - Look at your home folder again in the Finder.
- Feel a sense of normalcy return to the universe.
Serious suggestion though: how about if the Xcode installer did this for you?
