I do not understand what I am doing wrong?

I know I am wrong but the logic checks out?

struct Person {
    let firstName: String
    let lastName: String

    func fullName(ofPerson person: String = firstName + lastName) -> (String)

Hi, I just answered a fellow student with the same doubts you have. Be sure to search for answers in the community, almost always somebody else had a problem with the same challenge at some point. I know I did!

This is the same answer I gave the other person:

So here is where you went wrong. The instruction doesn't ask for parameters in your function, but you do need to return a string. So the set up for the method should look like this:

func fullName() -> String {

Now you need to set up a concatenation or interpolation of the string to return the full name.

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


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

Now you have to create an instance of Person using a let called aPerson with values of your choice:

let aPerson = Person(firstName: "Maria Angelica", lastName: "Dadalt")

And finally, you have to call on the method (or function, whichever you prefer), using the instance you created with a dot notation.

let myFullName = aPerson.fullName()

I hope this could help you!
