Overriding locale

Airship uses the user’s LocaleThe combination of a language and country. A user’s locale is determined by their device settings. for various locale-sensitive tasks, including selecting the language for messages and reporting for analytics. Apps can override the locale so that Airship uses a different locale than the device’s current locale. Note: Airship UI localization uses the device’s current locale, so it is not affected by the override.

Airship.shared.localeManager.currentLocale = Locale(identifier:"de")
UAirship.shared.localeManager.currentLocale = [NSLocale localeWithLocaleIdentifier:@"de"];
Clearing the locale override
[UAirship.shared.localeManager clearLocale];

NSLocale *airshipLocale = UAirship.shared.localeManager.currentLocale;
