Localization of app in language that is not in "Language" list in Settings.app

Question

Here is my issue:

I have 2 localizations - for English and for Bulgarian. I can't load Bulgarian languages, because it's not in "Language" list, and English is loaded even though the Region Format is set to "Bulgaria".

Is there a way to open my app with my bulgarian localization files or not?

Answer 1

As of at least iOS 8 you can change the order of languages in Settings > General > Language and Region under the heading Preferred Language Order.
