Question

Answer 1

You can build your own list of country codes and that country's currency symbol using the following code:

Objective-C:

- (void)listCountriesAndCurrencies {
    NSArray *localeIds = [NSLocale availableLocaleIdentifiers];
    NSMutableDictionary *countryCurrency = [NSMutableDictionary dictionary];
    for (NSString *localeId in localeIds) {
        NSLocale *locale = [NSLocale localeWithLocaleIdentifier:localeId];

        NSString *country = [locale objectForKey: NSLocaleCountryCode];
        if (country && country.length == 2) {
            NSString *currency = [locale objectForKey: NSLocaleCurrencySymbol];
            countryCurrency[country] = currency;
        }
    }

    NSArray *sorted = [countryCurrency.allKeys sortedArrayUsingSelector:@selector(compare:)];
    for (NSString *country in sorted) {
        NSString *currency = countryCurrency[country];

        NSLog(@"country: %@, currency: %@", country, currency);
    }
}

This code starts with the list of all locale ids. From there it creates each associated NSLocale. For each locale, the country code and currency symbol is extracted. These are used to build a dictionary of country codes and currency symbols which are then printed out.

Here's the same code translated to Swift 3:

func listCountriesAndCurrencies() {
    let localeIds = Locale.availableIdentifiers
    var countryCurrency = [String: String]()
    for localeId in localeIds {
        let locale = Locale(identifier: localeId)

        if let country = locale.regionCode, country.characters.count == 2 {
            if let currency = locale.currencySymbol {
                countryCurrency[country] = currency
            }
        }
    }

    let sorted = countryCurrency.keys.sorted()
    for country in sorted {
        let currency = countryCurrency[country]!

        print("country: \(country), currency: \(currency)")
    }
}

This results in the following list when run on a simulated iOS 10 device:
