4,806 PointsI feel like my code is right...
It's telling me to make sure my string interpolation is right, but I think it is...
struct Tag {
let name: String
}
let firstTag = Tag(name: "music")
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: "Blogs", author: "John Drexler", tag: firstTag)
let postDescription = firstPost.description()

11,831 PointsYou have to change your firstTag to "swift" and access it in the string interpolation using tag.name and it is asking for a string that prints "iOS Development. Filed by swift" like this:
struct Tag {
let name: String
}
let firstTag = Tag(name: "swift")
struct Post {
let title: String
let author: String
let tag: Tag
func description() -> String {
return "\(title) by \(author). Filed under \(tag.name)"
}
}
let firstPost = Post(title: "iOS Development", author: "Apple", tag: firstTag)
let postDescription = firstPost.description()

You're really close! You're just missing one thing! Inside of your description method, you are currently using String interpolation on the entire instance of Tag.
func description() -> String {
return "\(title) by \(author). Filed under \(tag.name)" // needs to read tag.name
}
What you need to be doing is accessing the name property of the Tag instance using dot syntax.
Hope this helps! Good Luck!
