Hi Karthik!

I had to do some digging on this one, but I was able to find what the issue is. The problem lies in the declaration of your function:

func getFullName() -> (String) {

For the challenge to work, the function needs to return a String, but what is being returned is actually a Tuple with a single member. This boils down to String and (String) being different types, with the parentheses on the latter making it the Tuple that I mentioned. I tested the code, and it went through as soon as I took them off.

I hope this helps, and Happy Coding!
