I have a question about localization: Does Apple deliver all language files to a device or only those based on the localization settings? That could be another area of app bloat.

Also, keep in mind that localization can also exist in graphical assets. You could have images with built-in text that need to be switched in based on localization. So, an English version of the app uses this set and an Italian version another set of assets. This might include sound files.

Depending on how this is handled it can start to explode the app bundle in impressive ways. Start with 100 images. Now you need 400 to cover all device display configurations. Then you need to replicate this on a per-language basis. If you cover, say, five languages, you are up to 2,000 files potentially delivered to every single device regardless of applicability. I realize that this is a corner case where all images need to be localized. No need to point that out.

I have not done any internationalization yet, so I don't know how this part works. For some cases it might not be practical to release a separate app in different languages. For example, a kids app that is able to operate in English and Spanish and sold through the US app store.
