The compiler keeps trying to say return a string but I believe I am returning a string and can't figure out the source

I am putting a string together within a init method and its keeps giving me an error saying that I am not return a string. I have ran the code in Xcode and it works fine.

structs.swift
struct Tag {
    let name: String
}

struct Post{
    let title: String
    let author: String
    let tag: Tag

     func description()->String{
        return "\(title) by \(author). Filed under \(tag.name)"
    }
}

let tag = Tag(name: "Science Fiction")
let firstPost = Post(title: "Dune", author: "Frank Herbert", tag: tag)
let postDescription = firstPost.description()

Brice, interesting case! What the compiler doesn't like is the lack of spaces in the function return.

You have:

     func description()->String{
        return "\(title) by \(author). Filed under \(tag.name)"
    }

This works:

    func description() -> String {
        return "\(title) by \(author). Filed under \(tag.name)"
    }

P.S., your version works in Xcode.
