Localization issue, duration always returned in english

Hey @etrality! Thanks for the clarification, I just tested this and it seems to work:

If you modify the `format` method from that Stack Overflow post to include a specific locale for the calendar, this translation will work as expected. Here’s my new `format` method I’m using:

    static func format(unit: NSCalendar.Unit, numberOfUnits: Int) -> String? {
        var calendar = Calendar.current
        calendar.locale = Locale.current // to test German: Locale(identifier: "de")

        var dateComponents = DateComponents()
        dateComponents.calendar = calendar
        componentFormatter.allowedUnits = [unit]
        switch unit {
        case .day:
            dateComponents.setValue(numberOfUnits, for: .day)
        case .weekOfMonth:
            dateComponents.setValue(numberOfUnits, for: .weekOfMonth)
        case .month:
            dateComponents.setValue(numberOfUnits, for: .month)
        case .year:
            dateComponents.setValue(numberOfUnits, for: .year)
        default:
            return nil
        }

        return componentFormatter.string(from: dateComponents)
    }

When I print the period method like this:

print(package.product.subscriptionPeriod?.localizedPeriod())

An Optional was printed to the console:

1 Jahr

Let me know if that works for you, too!
