I have an unlocalized shipping app which has foo.xib in the main project directory. In preparation for localization, I moved this to en.lproj/foo.xib. Now, when I build my
I just had the same issue but found a solution which works, even with Xcode's deployment quirkiness: Prevent UIViewController loading stale XIB from app bundle
I'm having the same issue. The problem is that the phone keeps a cache of the nibs. Somehow thus cache needs to be cleared for you to see the new localized nibs. I also don't want my users to have to delete the app since it stores data.
Answering my own question in case anyone else runs into this issue. It appears that this is an artifact of the Xcode build-publish cycle, and it isn't a problem when user's upgrade via the App Store. I went ahead and published my update and no one has noticed problems that would result from stale resources.
As a speedup to development, it appears that Xcode only copies over resources that it detects have changed when you build and install to the simulator or a test device. (To prevent a game with 500MB of resources from having to be re-copied each and every time you build and test.) When you (re)move a resource from a project though, it does not detect this and (re)move the old copy. I will file a bug with Apple about it.
However, the App store does appear to do a clean install with each upgrade (copying over the user's documents directory) so this is not a problem from the App Store. I'm not sure if it is a problem when emailing beta testers an .ipa file or not.
