问题
On iOS 9, the localization is not working well when more than 63 localization files are added. If you have minus than 63 files, the translation can work correctly, but when more than 63 files are added the Xcode doesn't call the correct language file, always calling base.
On my GitHub example project (https://github.com/munhra/iOSLocalizationExample), there are 64 localization files added to Xcode. If run the project, Xcode doesn't call the corresponding device language. If a translation file is removed, we can run the Xcode again e check that the application language is correctly, based on the device language settings.
