Hello, I want my app to support only one language - polish. The problem is some of built in components aren’t translated, for example when app asks for permissions they are in english despite phone’s language is polish. The problem occurs only for iOS, android is fine.
I think i need to set primary langue to polish but there is no such option in: iTunes Connect → My apps → App Store → App information → Localizable Information
i’m not an expert here but i think you can manually set locale through RN but then you might need to add i18n which you do not need since the app is in only polish.
I think we need to add support for this in our standalone app builder, as it requires configuring the iOS NSBundle to add a *.lproj directory. We’re tracking this and will add it when we get a chance.
Answer edited in 2018: We support adding .lproj localization directories to your native iOS build if you provide localized system strings for your app.
