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

Your Post struct needs to be created by passing in two strings and a Tag. While a Tag has a name property that is a String, the init method for a Post needs to handle a Tag object. That's what the challenge tests are passing to your code and it's failing because the Tag isn't being handled - your init method is taking three String instances.
So, when you create the instance of Post called firstPost, pass in the two strings as you have done, then create a Tag instance for the third argument. Something like tag: Tag(name: "Swift"). You'll need to handle that differently inside init too - but that's straightforward.
Steve.
