I understood the question and I did the right answer but the error is that to use string interpolation, and I used it.
struct Tag {
let name: String
}
struct Post {
let title: String
let author: String
let tag: Tag
func description() -> String {
print("\(title) by \(author). Filed under \(tag)")
}
}
let post = Tag(name: "Swift")
let firstPost = Post(title: "iOS Development", author: "Apple", tag: post)
let postDescription = firstPost.description()

15,970 PointsHi Raju,
you are close to the solution. These things need to be changed:
1) the description method should RETURN the description, not print it.
2) in the description method use the name property of tag (tag.name) instead of the instance (tag). The instance itself is not a string.
Good luck
