    let lastName: String

func fullName(firstName first:String, lastName last:String) -> [Person] {
        var result = [Person] ()

Hi David,

The challenge wants you to add an instance method to the "Person" struct.

Here's the correct code:

struct Person {
    let firstName: String
    let lastName: String

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

//This is the 2nd part of the challenge, but I'm including it to show you how you call the method

let aPerson = Person(firstName: "David", lastName: "Cruz")
let myFullName = aPerson.fullName()

firstName and lastName will be passed as arguments when the struct is instantiated (in the example above, you can see this on the "let aPerson..." declaration.

Since these properties are being set, the "fullName" method doesn't need any parameters. All it needs to do is return a string.

Now when you get to step 2 of the challenge, you will create a Person instance and pass the first/last name values of your choosing. Then you can call the fullName method on the aPerson object to get the concatenated fullName.

Hope that helps.
