There needs to be a space between your opening and closing curly braces around your get and set. See my solution here:

protocol UserType {
var name: String { get }
var age: Int { get set }
}

Thanks for your answer, but why the compiler is not showing any error??

Because as I understand it, it works fine in the compiler, but not in the challenge. Why the challenge doesn't accept your... I can't answer. I can only say what it will accept :)

Thanks again, the question is: In normal coding, do I need to use space as well or is it only for the challenge sake?

I've seen this in the compiler myself and it didn't require the spaces. So I think it's just the challenge :) But might be a good habit to get into? It doesn't hurt anything and it's pretty readable.
