I having some trouble with the object oriented swift

Can someone explain the logic behind a struct for me I have watched the videos a few times and don't seem to get it? Also, how can I create this method I am totally lost

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


func fullName(wholeName name: firstName + " " + lastName){

return fullName 

}



}

A struct allows you to make an exact copy of data as opposed to a (class) reference to the data. But, I wouldn't get caught up in that. I just kept working through the videos - and practiced - then it clicked. As for the method: The func doesn't take any variables, but remember, in Swift you specify the return type (in this case String). Then, the body of the function returns the two constants in the Person definition using String interpolation. Hope this helps.

struct Person {
    let firstName: String
    let lastName: String

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