IsoCountryCodes for Swift

Iso country codes - that thing that we discussed that defines codes for the names of countries, dependent territories, and special areas of geographical interest.

What?

This is a iOS Swift library/class files that does a simple lookup depending on a alpha2, alpha3 or numeric value you give it. Currently it holds all the 249 countries, territories, or areas of geographical interest that are assigned official codes in ISO 3166-1.

Features:

This library returns ISO codes, names and currencies for countries.

• Find by alpha-2, alpha-3 or numeric (String - yes I know...)
• Search by (partial) name, case- and diacritic insensitive
• Search by currency code
• Search by phone dialing code (+31 for Netherlands, +1 for USA, etc...)
• Retrieve a corresponding emoji flag for a country code.
• Retrieve a fraction digits for a country's currency. This can be useful when converting an amount in a certain currency to digits (ex 1 euro = 100 cent)

Usage:

You can search via numeric, alpha-2 or alpha-3 format. Searching an ISO code returns a struct.

print(IsoCountryCodes.find(key: "020").name) //Andorra
print(IsoCountryCodes.find(key: "TK").name) //Tokelau
print(IsoCountryCodes.find(key: "TKL").currency) //NZD

You can also search by country name, currency or calling/dialing code:

dump(IsoCountryCodes.searchByName("Netherlands")
print(IsoCountryCodes.searchByCurrency("EUR").count ) // 31
print(IsoCountryCodes.searchByCallingCode("+31").first ) // Netherlands

let country = IsoCountryCodes.searchByName("Netherlands")
dump(country) // This dumps the full struct in console

This returns a IsoCountryInfo struct:

▿ IsoCountryCodes.IsoCountryInfo
    - name: Netherlands
    - numeric: 528
    - alpha2: NL
    - alpha3: NLD
    - calling: +31
    - currency: EUR
    - continent: EU

Searching by name is case- and diacritic insensitive:

dump(IsoCountryCodes.searchByName("netherlands"))
dump(IsoCountryCodes.searchByName("NETHERLANDS"))

dump(IsoCountryCodes.searchByName("Réunion"))
dump(IsoCountryCodes.searchByName("Reunion"))

If no full match is found, a partial match is tried:

// Full name is "Venezuela, Bolivarian Republic of"
dump(IsoCountryCodes.searchByName("Venezuela"))

but nothing is returned if the search results would be ambiguous:

// There are two Virgin Islands country codes:
// "Virgin Islands, British" and "Virgin Islands, U.S."
dump(IsoCountryCodes.searchByName("Virgin Islands"))

Fun with flags

Retrieve a corresponding emoji flag from a country code. (Thanks to @lorismaz for this addition!)

let emojiString = IsoCountries.flag(countryCode: "NL")
// Prints 🇳🇱

or

let emojiString = IsoCountryCodes.find(key: "USA").flag
// Prints 🇺🇸
