title: Getting country name from country code
body: <p>I have found the answer for this for objective-c but Im having a hard time doing this in swift. </p>
  
  <p>I have used this to get the country code for the current location:</p>
  
  <pre><code>     let countryCode = NSLocale.currentLocale().objectForKey(NSLocaleCountryCode) as! String
      print(countryCode)
  // printing for example US
  </code></pre>
  
  <p>But how do I convert this country code to a country name, like in this example converting "US" to "United States"?</p>
