>iOS apps also need to include all localized assets in each app bundle.
Is this a hard requirement? I use two languages or at best three. The other 100 language don't matter to me. Why do I have to waste space on my smartphone. This adds up if I have hundreds of apps.
It is the default.
You could get localizations OTA, but that's engineering you need to do to make that happen.. or a product you purchase, as there's various localization managers offering these options in their software.
