The struct Person conforms to the protocol User so the struct must have the the properties that are in the protocol and then you must create an instance of Person and assign it to a constant named somePerson.

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

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

let somePerson = Person(name: "Any name", age: 5 )
