1,207 PointsHow do you want me to write a method to return an entire struct as a string? Instructions are unclear.
I can write this a number ways, and I don't think the question is supposed to return fully functioning code, but nothing I've tried has worked, even if there are no errors in my code. The question suggests I should be writing out the string ("allow for a space..."), but no way that I've written it is working and I'm not finding any help online since this is a specific challenge.
I've tried changing the return type to 'String' or an array of the structs '[Person]'. I've structured the instance of the struct within the method a number of different ways with no success. I've tried keeping it as simple as possible and inline with the previous lesson, but nothing works.
The error returned doesn't make sense. Even if the code returns no error in the Preview the same error returns in editor shrug I'm at a loss. I'm just lost on what is being asked for here.
Thanks
struct Person {
let firstName: String
let lastName: String
}
func fullName() -> (Person) {
let fullName = Person(firstName: "Name ", lastName: "Name2")
return fullName
}

1,207 PointsThanks Michael, it still returns "Make sure your method returns the correct string, including a space between the first and last name". Space is included in the return string, but it seems it still not the expected format.

Python Development Techdegree Graduate 38,552 PointsHave you got something like this?
struct Person {
let firstName: String
let lastName: String
func fullName() -> String { //fill in here }
}
Elizabeth Hernandez
1,207 PointsSorry, for the delay Michael. Here is what I have:
struct Person { let firstName: String let lastName: String
func fullName() -> String {
let name = Person(firstName: "Name ", lastName: "Name2")
return ("\(name.firstName) \(name.lastName)")
} }

1,207 PointsI've simplified the return to:
return ("(name)")
This works as code, but still fails the challenge.

Python Development Techdegree Graduate 38,552 PointsYeah, that would work in xCode. But for the challenge you could just return 'firstName' and 'lastName'. So it'll look something like this -
struct Person {
let firstName: String
let lastName: String
func fullName() -> String {
return firstName + " " + lastName
}
}

1,207 PointsThank you Michael! That worked! I had attempted something like that, but I the formatting I used for the return as incorrect. I've never used that formatting before. Good to know.

1,207 PointsAlso fails:
func fullName() -> String {
}
Error suggest my method either takes parameters or doesn't return a string, which as far as I understand, neither apply.
