//This Code is correct, but can't move forward. It happens sometimes as their (TTH's) site is looking for specific a process (or syntax). If anyone can tell me the specific way TTH wants this written- that will be nice! Thanks...

struct Person { let firstName: String let lastName: String

func fullName () -> String {
    let  fullName = "\(firstName) \(lastName)"

    return fullName
}

}

let example = Person(firstName: "Annie", lastName:"Jones") example.fullName()

Your syntax is correct except it wants specific constants. Reread challenge two and it will tell you to create two constants. One named aPerson and one named myFullName:

struct Person {
    let firstName: String
    let lastName: String
    func fullName() -> String {
      return "\(firstName) \(lastName)"
    }
}

let aPerson = Person(firstName: "Billy", lastName:"Boo")
let myFullName = aPerson.fullName()

Hey Matt, Thanks for reply! Unfortunately the challenge text does not include that. Here is what is reads

"Given the struct below in the editor, we want to add a method that returns the person’s full name. Declare a method named fullName() that returns a string containing the person’s full name. Note: Make sure to allow for a space between the first and last name"

Though I will make the changes to move-forward. After applying that and moving the next part did mention as you wrote it. Thanks again

Sorry. It appeared that you were already on challenge two because you were creating an instance of Person and using the method you created in challenge one. That is the objective of challenge two:

Let's use the struct to create an instance of Person and assign it to a constant named aPerson. Assign any values you want to the first and last name properties. Once you have an instance, call the instance method and assign the full name to a constant named myFullName.

The reason you were having trouble with challenge one is the space between your function name and the parentheses. Remove that space and challenge passes

Ah! white space sensitivity with TTH. Thanks, I will keep an eye for that.
