You are close. A couple of changes:

1) Don't provide values for the firstName, lastName properties in the struct (you will pass those values as arguments when you instantiate the struct as "aPerson")

2) The fullName() method call needs to be called on the aPerson object

Here's the corrected code:

struct Person {
    let firstName: String
    let lastName: String

    func fullName() -> String {
      return firstName + " " + lastName
    }
}

let aPerson = Person(firstName: "Justus", lastName: "Alberson")
let myFullName = aPerson.fullName()
