354 PointsHelp with function method
I'm having issues with the exercise. The previous exercise on functions does not go over some of the function specifics that are used in this object lesson so i'm a little confused about how to specify my function. I don't understand how my function should return the name? For instance, in a previous lesson on functions we used print to create the output. Here we are specifying a return type as a custom type, which is necessary for this method?
struct Person {
let firstName: String
let lastName: String
func fullname(firstname: String = "Ed", lastname: String = " Watson") -> [Person] {
}
}

Your method doesn't need to take any parameters as it can access the two member variables directly. It wants to return the representation of the full name, which is of String datatype.
I'd use interpolation inside the method to return "\(firstName) \(lastName)". You could concatenate, adding a space in between, if you prefer.
So, create your method, state no parameters, make it return a string and use the above line inside the method - that should work.
Let me know how you get on.
Steve.

354 Pointsthis doesn't work:
struct Person {
let firstName: String
let lastName: String
func fullName(firstname: String, lastname: String) -> String {
return firstName + " " + lastName
}
}

If you get rid of the parameters that you are requiring the function to receive, that will probably work.
So, lose what's inside the parentheses, but leave the parentheses in place. Your method doesn't need to receive firstName or lastName because it is within the class and can see them directly.
The rest looks fine.
Keep me posted how you get on.
Steve.
