Again, totally lost here. Any help would be appreciated.

Again, I'm at this point of having no idea what to type BUT if someone placed the answered question in front of me I could read it fine AND I would probably feel stupid because it would seem so obvious. It's like, I can read the code but I cannot write it to save my life. Also, as I've mentioned in a previous question post I feel there is a disconnect between the videos leading up to the tasks and then the tasks themselves. It's like, some good task might be just getting you to repeat out some of the previous material so you can get used to typing the data etc, and this is coming from someone who is copying every single thing in the videos religiously.

Any case, if someone could help point me in the right direction for getting the logic on this that would be awesome.

struct Person {
    let firstName: String
    let lastName: String

    func fullName(firstName, lastName) {
      return.fullName
    }
}
