I'm not sure why it's not compiling

There seems to be something wrong with the compiler.. It's telling me to make sure I'm doing String interpolation on description but I am.. help?

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)" } }

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

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)"
}
}

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

This works as well. Sorry for the confusion.

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

Very close my friend. You just need to fix this line up a bit.

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

Oh, awesome. thanks. But, why put in ()? I wrote in Swift (Xcode 8.3.1) and it didn't make me do that.. I wrote it like I did above.
