Method Quiz

I am really lost here, if someone could show me how to do it and explain why that would be absolutely amazing.

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

Ok. Here is how your code would look. Pay attention to the fact that the "method" is a function inside of the struct. Also I am using string interpolation to make the full name return string. You could use string concatonation (fullName + " " + lastName) also.

See at the end we create your person object and we call the method on that object instance to get your fullname back from that function. :)

struct Person {
    let firstName: String
    let lastName: String

    func getFullName() -> String {  // Here is our method with our return.
        return "\(firstName) \(lastName)"  // Here is our return.
    }
}

// Now e create an instance of the person passing the parameters in.
let aPerson = Person(firstName: "Israel", lastName: "Bracey")

// Now we call the instance method to get the fullname as a string.
let fullName = aPerson.getFullName()

I hope this helps. :)
