Hello!

It seems that the challenge is asking for Person to conform to the protocol User.

You started off great with adding: 

struct Person: User

User has two variables: 'name' and 'age'. Thus, Person must conform to those variables by including 'name' and 'age' in it's struct. This is done like so:

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

struct Person: User {
  var name: String
  var age: Int
}

Finally, you test everything with an instance of Person named 'somePerson'

let somePerson = Person(name:"Test", age:21)

Hope this helps!
