iOS Development Techdegree Student 4,037 PointsI'm not sure why it's not compiling
There seems to be something wrong with the compiler.. It's telling me to make sure I'm doing String interpolation on description but I am.. help?
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)" } }
let firstPost = Post(title: "iOSDevelopment", author: "Apple", tag: Tag(name: "swift")) let postDescription = firstPost.description()
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)"
}
}
let firstPost = Post(title: "iOSDevelopment", author: "Apple", tag: Tag(name: "swift"))
let postDescription = firstPost.description()

return "\(title) by \(author). Filed under \(tag.name)"

return ("\(title) by \(author). Filed under \(tag.name)")

iOS Development Techdegree Student 4,037 PointsOh, awesome. thanks. But, why put in ()? I wrote in Swift (Xcode 8.3.1) and it didn't make me do that.. I wrote it like I did above.

iOS Development Techdegree Student 4,037 Pointsoh, ok. I see what I missed: tag.name. I just put tag. Thank you!
