returns optional(+1)

[ghost]

This was very helpful for me.I am new to IOS. I am now migrating to swift 3. In previous version I did not get any optional value. I got output as flag US +1 now I am getting output as US +optional(+1).I need to update the text field with the country selected once the view is ready There is function to change the label text when the picker view triggers select action but How to initially display the country when the view is loaded.Can you please help me with this.

Try the following change in CountryPicker.swift file it worked for me

func countryNamesByCode() -> [Country] {
...
...
let phoneCode: String! = "+\((phoneNumberUtil?.getCountryCode(forRegion: code))!)"
...
...
}

Use like this

if let myCodes = phoneNumberUtil?.getCountryCode(forRegion: code) {
            
         let phoneCode : String = String.init(describing: myCodes)
}
