I'm using string interpolation to return the exact phrase it is looking for and it continuously gives me errors. help

I'm fairly certain I'm doing this correctly and it is just not recognizing it properly, however, i may not be. Please help.

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

The issue is that tag contains an instance of the Tag struct, to get the name out of the tag you need to use tag.name not simply tag.

So your description function should look like this:

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