I assume you are having trouble with the first part of the challenge. There are several issues with your answer:

  1. The fullName method needs to be declared inside of the Person struct.
  2. There is no need to put the return type within brackets.
  3. You do not need to create an additional constant to return, just return firstName and Lastname as a combined String.
struct Person {
    let firstName: String
    let lastName: String

  func fullName() -> String {

    return "\(firstName) \(lastName)"
  }
}

let aPerson = Person(firstName: "John", lastName: "Smith")
let myFullName = aPerson.fullName()
