country picker swift 4 : <p>I would like implement a native iOS country picker in swift 4. 
Currently I have a table which contain the countries code: </p>

<pre><code>var countriesCodes = NSLocale.isoCountryCodes as [String]
</code></pre>

<p>I implement the delegate, and I have a problem in the data source. 
How to convert each country code in country name?</p>
