Hey Sean you wrote out the struct Post giving Tag a default name and thats one thing not letting you pass the challenge. The other thing is when you write out the return statement for the method. You have to call the name property since tag is a stored property of Post and its type Tag. When you use string interpolation you have to specify the property with dot notation. It should be written like this.

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)"

        // if you only put \(tag) it won't come out right
       // it will print out, Red Wheelbarrow by Mr. Robot. Filed under Tag(name: "robot")
      // adding .name makes it print out the correct phrase 
     // the phrase you want it like this,  Red Wheelbarrow by Mr. Robot. Filed under robot

    }


}

let firstPost = Post(title: "Red Wheelbarrow", author: "Mr. Robot", tag: Tag(name: "robot"))

let postDescription = firstPost.description()
