11,303 PointsI can't get the Tag type to read correctly in my string assigned to postDescription.
I've tried initializing the Post struct with no different results. I'm not sure how I can get the sentence to read as "In Cold Blood by Capote. Filed under mystery" instead of "In Cold Blood by Capote. Filed under Tag(name: "mystery")". I don't know how to access the value for tag as a value type of Tag in my firstPost instance to properly use in my string.

Have a look at this solution to see if that makes sense to you:
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:"iOS Development", author:"Apple", tag: Tag(name: "swift"))
let postDescription = firstPost.description()
Accessing the name
property of the tag
instance is done with dot notation inside the string interpolation.
I hope that makes sense?
Steve.

11,303 PointsOh man, that's it! I thought I tried that but I was actually trying to use the capitalized Tag from the original struct declaration.
Thank you for the clarification!!!
