Hey, I’ve added a function to the structure which should be able to concatenate the firstName and lastName strings, but I’m getting an error saying that I haven’t added a function to the structure. Please advice!
struct Person {
let firstName: String
let lastName: String
func fullName(firstName: String, lastName: String) -> String {
let results = "\(firstName) \(lastName)"
return results
}
}

The firstName and lastName that the method should concatenate are the ones that already exists within the Person struct. Since the method is also inside that struct it can access them directly without being passed any data.
Like this:
struct Person {
let firstName: String
let lastName: String
func fullName() -> String { // Declare fullName method with no parameters
let results = "\(firstName) \(lastName)" // Return `firstName` and `lastName` from struct
return results
}
}
