Localization on iOS
Assistive technologies, such as the screen reader, use the locale for the pronunciation of utterances. It is important to explictly set a locale for your app. An incorrect locale leads to unclear pronunciation. Also, setting a locale can help with displaying characters correctly.
On iOS, you can set the locale of an app via the CFBundleDevelopmentRegion property. We suggest using Base internationalization to separate user-facing strings from .storyboard and .xib files. You can load a specific Bundle to load assets in the desired language.
