how to make a instance method?

Instance method is still confusing me. Can someone explain it to me?

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

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

they want a function that takes no parameters and returns a string. remove your params, return one string instead of two, and change the body to concatenate firstname (not fullname), a space, and lastname.

so I did all of those things and it makes sense now. But it's saying to make sure there are no parameters and returns a string. the params where the things in the () after fullName. so it should look like this fullName() right? and for the body it looks like this return firstName lastName right?
