What's wrong in my code? works in xCode but doesn't in the compiler (1st challenge)

struct Tag { let name: String }

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

func description() -> String{

    return("\(title) by \(author). Filed under \(tag.name)")
}
}

let firstPost = Post(author: "Apple", title: "iOSDevelopment", tag: Tag(name: "swift"))

let postDescription = firstPost.description()

structs.swift
struct Tag {
    let name: String
}

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

    func description() -> String{

        return("\(title) by \(author). Filed under \(tag.name)")
    }
    }



let firstPost = Post(author: "Apple", title: "iOSDevelopment", tag: Tag(name: "swift"))

let postDescription = firstPost.description()

Hi there! Your code is functional and will work inside Xcode. But challenges can be very strict sometimes. In fact, your code passes if simply reordered. Treehouse is expecting the declaration of the title before the author. So if we reorder it like this:

    let title: String
    let author: String
    let tag: Tag

And then we reorder how we pass in the arguments like this:

let firstPost = Post( title: "iOSDevelopment", author: "Apple", tag: Tag(name: "swift"))

The challenge will pass. Hope this helps! :sparkles:
