In iOS app development, I could't find the official way to set fallback localized language. I want to use English when user language is not included in my app's localizations. I tried way to use Base Internationalisation, however, all doesn't work for all language. Now, replace base.lproj to en.lproj, only languages added into my app are work well, but other languages are doesn't work well. (English not used, instead Korean is used when select a Russian...)
Some sites say that, set fallback language with value of "Localisation native development region", However, it didn't work well. Do you have any idea? Thanks.
