Locale not changing the language

Describe the bug Hello, I’m using Luxon in React-Native project on IOS simulator. I’ve set Settings.defaultLocale = 'fr' to have my date to french translations. But seems to not working, I always got english translations. I’ve also tried to directly modify the local in the parameters, same result.

To Reproduce

import { Settings, DateTime, Info } from "luxon";

Settings.defaultLocale = "fr";

console.log(
  "DateTime.now().locale =",
  DateTime.now().locale,
  "Info.months =",
  Info.months("long", { locale: "fr" })
);

Actual vs Expected behavior Have dates in french language

Desktop (please complete the following information):

• OS: IOS 14.5
• Browser [e.g. Chrome 84, safari 14.0]
• Luxon version : 1.27.0

Thank’s for any help.

You’ll need to make sure that ICU is getting loaded into your environment, because Luxon uses internationalization capabilities built into the environment, using the Intl API. For example, they come built into the browser and newer versions of Node. I’m not sure how to do that in the iOS simulator, though.

I’ve the same issue when trying Info.months('long', {locale: "es-ES"}) or Info.months('long', {locale: "es"}) for Spanish

The array it returns is just 12 null values: [null, null, null, null, null, null, null, null, null, null, null, null]

Environment MacOS: 13.0 Simulator: iOS 16.0 React native version: 0.70.3 Luxon version : 3.1.0
