struct Tag { let name: String } struct Post { let title: String let author: String let tag: Tag func description() -> String { let desc = "(title) by (author). Filed under (self.tag)" return desc
} }
let firstPost = Post(title: "iOS Development",author: "Apple",tag: Tag(name: "swift")) let postDescription = firstPost.description()
struct Tag {
let name: String
}
struct Post {
let title: String
let author: String
let tag: Tag
func description() -> String {
let desc = "\(title) by \(author). Filed under \(self.tag)"
return desc

Treehouse TeacherHi there! You're doing really well here and you are soooo close here. The problem is in the part where you're interpolating self.tag. The variable tag holds a an instance of the struct Tag. It can't be interpolated as a whole. What needs to happen here is you need to interpolate the stored property of that struct. In this case, the name property.
I believe you can get it with these hints, but let me know if you're still stuck!
