It\'s been 2 days this issue is driving me nuts.
I\'m trying to localize my iOS app but for the life of me I can\'t get it to work. It works easy enough when I try o
It looks like you already figured this out, but I think what probably happened is that originally you had "MainStoryboard.storyboard" as an unlocalized resource. This means that when you build your app, you get a "MainStoryboard.storyboardc" as an unlocalized resource. When you change your storyboard to be localized, you get a "Base.lproj/MainStoryboard.storyboardc" in your bundle resources.
There are several copies of your app when you're building in Xcode. There's the copy on your device or in the simulator, and there's also a copy in your derived data folder in Xcode. When you do an incremental build of your application, the copy in the derived data folder in Xcode is a merge of your new content and your old content. So, when you modify a resource in Xcode, and rebuild, you get the newest resource. However when you rename or delete resources, the old copy is still left in the build directory until you perform a clean operation.
This means that your build product probably had both "MainStoryboard.storyboardc" and "Base.lproj/MainStoryboard.storyboardc". When NSBundle loads resources, it prefers unlocalized content, and would load the old "MainStoryboard.storyboardc".
