FlagPhoneNumber: Library Crash

App crash due to this function, mostly first time when its loads.

func setCountryByRow(row: Int) {
		self.selectRow(row, inComponent: 0, animated: true)
		let country = countries[row]
		if let countryPickerDelegate = countryPickerDelegate {
			countryPickerDelegate.countryPhoneCodePicker(self, didSelectCountryWithName: country.name!, countryCode: country.code!, phoneCode: country.phoneCode!, flag: country.flag!)
		}
