Use the users iOS currency settings

Question

I'm working with currency in an app and instead of listing out supported currencies or using Locale.isoCurrencyCodes to list out all currencies supported by iOS I would like to just use the currency that the user selects as their default system currency.

Is there a good way to do this or what's the best way to support multiple currencies in an iOS app?

For added context the application is written in Swift.

Local currency code:

let usrRegionCode = Locale.current.currencyCode!

E.g.: "USD"

---

Local currency symbol:

let usrRegionCode = Locale.current.currencySymbol!

E.g.: "$"
