Instance Methods

Help, I'm stuck! Maybe I'm just beyond my understanding of swift but I can't seem to grasp the calling of these methods. Am I supposed to create a function INSIDE the struct that clusters the information properly and then return that?

structs.swift 
struct Person {
    let firstName: String
    let lastName: String
}
let fullName = Person(firstName: "wes", lastName: "jacobs")

Thank you. Here's my code for the second part: 

struct Person {
    let firstName: String
    let lastName: String

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

let myFullName = aPerson.fullName()

Underneath your answer, I assigned an instance of the Person structure to a constant named aPerson.

Since we can only use these methods on INSTANCES of the class, then I called the fullName method on this new 'aPerson' and assigned it to another variable. I dunno if this helps. I'm sorta confused myself.

That's what I got too. I'm still piecing together how that worked. Haha

struct Person { let firstName: String let lastName: String func fullName() -> String{ return "(firstName) (lastName)"

}

}

This got me past the first part of the quiz but now i'm stuck on the second.
