I\'ve recently upgraded from Xcode 3 to Xcode 4.2, and migrated an existing iOS apps to use this new version. This app is localized, and I now want to add another language.
The file structure on disk is mostly irrelevant in Xcode. Just move the directory in Finder, then in Xcode you can either: (a) remove the fr.lproj directory and re-add it, or (b) select the red entry, open the right-hand (properties) panel, and near the top you should see the path. Change the path to the new location and it'll go back to black.
