Xcode 10 ? Swift 4.2 or later

extension Locale {
    static let currency: [String: (code: String?, symbol: String?, name: String?)] = isoRegionCodes.reduce(into: [:]) {
        let locale = Locale(identifier: identifier(fromComponents: [NSLocale.Key.countryCode.rawValue: $1]))
        $0[$1] = (locale.currencyCode, locale.currencySymbol, locale.localizedString(forCurrencyCode: locale.currencyCode ?? ""))
    }
}

Locale.currency["US"]   // (code "USD", symbol "$", name "US Dollar")
Locale.currency["BR"]   // (code "BRL", symbol "R$", name "Brazilian Real")
Locale.currency["GB"]   // (code "GBP", symbol "￡", name "British Pound")
Locale.currency["PT"]   // (code "EUR", symbol "€", name "Euro")
