Fire does not seem to correctly handle folders like “English.lproj” correctly.
These should be copied (with their contents) to the resources folder in the app bundle intact. Currently it looks the xibs inside are copied to the top level of the resources folder and the InfoPlist.strings and Localisable.strings are set with “No Action” by default (and so are dropped).
I haven’t checked but similar .lproj folders exist on iOS so maybe they aren’t handled correctly there?
