How to get list of available languages ​​from Localizations project?

Question

iOS

Good afternoon.
I created localization strings for the application in swift 4.

Now I want to display UIAlertControllerStyle.actionSheet with a list of these languages.
Please tell me how to do this, I can’t find an implementation anywhere on the network, and manually creating let availableLanguages ​​= ["ru" : "Russian", "en" : "English"] is not convenient if more languages ​​​​are added later.

Answer 1

let availableLanguages = Bundle.main.localizations as [String]

list of all available languages

let availableLanguages = Bundle.main.preferredLocalizations as [String]

list of available languages ​​based on system settings
