Description: Learn how your app can support per-app language settings in iOS 13. Get the details on localizing assets with asset catalogs and simplifying your localization workflow with Xcode 11. Understand how to generate screenshots in multiple languages for localization and testing.

Users can now change the language setting per app, this is huge! Available both on macOS and iOS.

This setting is in the system setting, we can forward the user there by calling: UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!)

Once the language has changed, the app will be relaunched with the new language preference.
