Correct Language Codes (ISO-639)

The following language codes should be used to name your localized resource folders.

xx.lproj

In earlier versions of OS X Apple used full English name versions for resource folders. That is why you’ll often see, especially in apps that have been around a long time, “English.lproj” resource folders. Apple now recommends you use the ISO / IETF naming convention:

The language code is based on the ISO 639-x/IETF BCP 47 standard. ISO 639-1 defines two-character codes, such as “en” and “fr”, for the world’s most commonly used languages. If a two-letter ISO 639-1 code is not available, then ISO 639-2 three-letter identifiers are accepted as well, for example “haw” for Hawaiian.
