2,354 PointsHaving trouble returning strings
I am having trouble with the 1st part of the challenge on Structs. I have setup the function and have set the function for return types of two Strings with names firstName and lastName. Inside the body of the function, I have set the function to return those variables. The challenge is telling me to make sure my function has no parameters (which it does not) and that it is returning a String. I am assuming I am not supposed to do anything inside the function, even though the challenge asks for a complete full name. Here is where I currently am:
struct Person {
let firstname: String
let lastname: String
func getFullName() -> (firstname: String, lastname: String) {
return (firstname, lastname)
}
}
struct Person {
let firstName: String
let lastName: String
}

Treehouse Moderator 145,860 PointsHey Kevin,
You're kind of on the right track. First off, your return statement is a bit off. You can't include variables/constants in the return type... only the type.
Second, your return statement is in the correct place, but you need to return a concatenated string that includes a space between the first name and last name.
Below is the correct code. Have a look, and I hope it makes sense. :)
struct Person {
let firstName: String
let lastName: String
func getFullName() -> String {
return (firstName + " " + lastName)
}
}
Keep Coding!

2,354 PointsThanks Jason! Another question: In previous videos, Pasan talks about setting up your return in the function declaration with names. Is that not appropriate here?

I watched the 2 videos prior to the quiz and was not able to find what you are referring to. In both videos, the return type of the function he has is a
Point(or more specifically an Array of Points).If you could provide a link to the video you're referencing and a time-stamp, I'll have look. :)
