Locale codes for iPhone lproj folders
Where would I find a list of locale name abbreviations for my project localization folders? (Such as en for English, fr for French).
I am looking to do German, Spanish and others.
Answer
You can just call them English.lproj, Spanish.lproj, etc.
The "abbreviated names" are actually IETF language tags (i.e. BCP 47), except that you use pt_PT.lproj instead of pt-PT.lproj.
The actual interpretation routine is in https://github.com/apple/swift-corelibs-foundation/blob/master/CoreFoundation/PlugIn.subproj/CFBundle_Locale.c, determined by the CFBundleGetLocalizationInfoForLocalization function. Replicated here:

Here:
- L# is the language code and C# is the country code. I consider two identifier identical if they share the same language and country code.
- I have only listed strings appearing the source file. It also recognizes something like
zh_HKandTraditional Chinese(both have same code number aszh_TW), probably through the more sophisticated CFLocale list.
