Need help: what would be the way to create a method here... thank you!

is it func?

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

    func getFullName( : String) {
    }

}

The function doesn't need any parameters because it has access to the firstName and lastName member variables in the struct. But it does need to say that it's returning a String. then it needs to combine the first and last names into a String.

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

Here I used String interpolation to do the combining. And notice the space between the two interpolated variables.
