   self.countriesViewController.delegate = self
   self.countriesViewController.allowMultipleSelection = false
   if let info = self.getCountryAndName() {
       countryCode = info.countryCode!
       self.lblFlag.text = info.countryFlag!

let base : UInt32 = 127397
var string = ""
let country = countryCode.uppercased().unicodeScalars
for uS in country {
    print("country code:\(countryCode.uppercased())---\(UnicodeScalar(base + uS.value)!)")
    string.unicodeScalars.append(UnicodeScalar(base + uS.value)!)
}

return string

    let phoneTest = NSPredicate(format: "SELF MATCHES %@", phoneRegex)
    return phoneTest.evaluate(with: phone)
}
