Not able to get this code to return the first and last name

Not sure what I need to change?

structs.swift 
struct Person {
    let firstName: String
    let lastName: String
}

func getFullName(name1: String) -> [Person] {
    var fullName: [Person] = []
        let name2 = Person(firstName: "Carl ", lastName: "Smith")
        fullName.append(name2)
    return fullName
}

let fullName = Person(firstName: "Carl ", lastName: "Smith")

The func needs no parameter, as it will get the first and last names from the struct's member variables. The function will return whatever first and last names have been stored in these member variables by the default constructor:

struct Person {
    let firstName: String
    let lastName: String

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

let aPerson = Person(firstName: "Carl", lastName: "Smith")
let fullName = aPerson.getFullName()

Thank you, that was getting really confusing for me. Now that I see how you did it, I got a better understanding.
