struct Person {
let firstName: String
let lastName: String
func fullName() -> String {
return "\(firstName) \(lastName)"
}
}
let aPerson = Person(firstName: "", lastName: "")
let myFullName = aPerson.fullName()

NOW you can call your instance methods on it. so the second part, assign to the constant myFullName your Person with the fullname method called on it using the dot notation.
