A few things there - but you've done the hard bit!!
First, your description
function should return a String
not a Stirng.
Second, the func
needs to be inside the curly braces of the struct
.
Lastly, in your interpolation, you want to use the name
property of the Tag
instance called tag
. Use dot notation like \(tag.name)
.
I think that's it ... I'll quickly check now.
Steve.

You also need the description function to be in your Post struct, so you can call it on firstPost. Lastly in you description func, instead of using the 'name' property you need to access it from the 'tag' property you created, 'tag.name'
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.name)"
}
}
let firstPost = Post(title: "iOSDevelopment", author: "Apple", tag: Tag(name: "swift"))
let postDescription = firstPost.description()
