title: How to get country phone code for given country name in Swift iOS?
body: <p>I'm working on a project 
  I need to send the selected phone number (which user selected already from phone contacts list) to the sever with format : 
  international-code-without-zeros-or-plus_the-number
  so I need to handle many cases : number without international code , number with zeros , number with plus , number with two zeros ..etc
  the problem is when I have a local phone number unprecedented by country phone code,I could get the current country name (country name code) if the device has a valid sim card via this code</p>
  
  <pre><code>let networkInfo: CTTelephonyNetworkInfo = CTTelephonyNetworkInfo()
  let ar = networkInfo.subscriberCellularProvider
  if ar != nil {
  if  let mcc = ar.mobileCountryCode {
      myInformation.countryCode = mcc
      }
  </code></pre>
  
  <p>then how can I get the country phone code?? </p>
