Tried following it is working but don't know how to do it with variable as there can be multiple values.

selectContryTextField.text = "\u{1F1E6}\u{1F1E9}"

Where do the values for `countryFlag1` and `countryFlag2` come from? It would be a lot easier if you avoided such a format. – rmaddy Jun 25 '19 at 16:01
they are coming from json response – amodkanthe Jun 25 '19 at 16:02
Why doesn't the JSON encode those characters in a standard way using `\u1F1E6`, etc.? Then when you parse the JSON in your Swift code, you will get the expected characters without any extra processing. – rmaddy Jun 25 '19 at 16:09
