String Interpolation?

I am doing the first code challenge for the Fun Facts app to test my understanding of object oriented programming. I believe I have all of the logic correct but for some reason it's saying that I'm not returning the right sting. Im not sure why. The challenge says for example, given a title: ''iOS Development", author: "Apple", and a tag named "swift", the description would read "iOSDevelopment by Apple. Filed under swift". I hope someone can see my error.

Hi Jason!

Do you mind pasting your code here into the forums so we can see what you are having problems with?

It should look something like this:

print("\(title) by \(author). Filed under \(tag)")

I'm not sure if I have used the proper variable names there but the basic outline should work fine.

struct Tag { let name: String init(name: String) { self.name = name } }

struct Post { let title: String let author: String let tag: Tag

init(title: String, author: String, tag: Tag) {
    self.title = title
    self.author = author
    self.tag = tag
}

func description () -> String {
    return "\(self.title) by \(self.author). Filed under \(self.tag)"
}

}

let firstPost = Post(title: "iOS Development", author: "Apple", tag: Tag(name: "swift")) let postDescription = firstPost.description() print(postDescription)
