My code works in the playground but not accepted here

Prints "iOSDevelopment by Apple. Filed under swift" exactly as it should. It may have to do with the fact that I created a constant to hold a version of Tag? Thanks in advance for any help

Julian, try something like this:

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: "swift")
let firstPost = Post(title: "iOS Development", author: "Apple", tag: tag)

let postDescription = firstPost.description()
print(postDescription)

Thank you jcorum! That works great. I can't see the original code anymore, but I'm thinking I didn't declare a version of tag as a constant like you did here. Instead I was trying to pass a value for tag in the firstPost constant, which seemed to work, but I couldn't call it with "tag.name" in the decsription() func
