What's the question specifically asking, Faiyaz?

First, I think the compiler requires a space in the syntax, second age needs to be gettable and settable, so instead of this:

protocol User {
    var name: String{get}
    var age: Int{get}
}

Do this:

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