“Set Language and Locale” sets the Language, dialect and Locale, providing the ability to repurpose a single iOS backup for worldwide use.
Select this item to proceed to the language selection window:
You must enter the codes (e.g. en_US) in the text boxes. You may also use data from Attributes.
Apple uses a variation on ISO codes for language and locales. For more information, see the iOS Developer Library article, “Language and Locale IDs.”
Note: Apple occasionally adds new languages and locales to iOS Updates, so older versions of iOS may not support all languages. A deployment containing an unsupported code will fail.
The Set Language setup screen is skipped automatically if the Workflow contains either a “Restore from Backup” action or an explicit “Set Language” action.
