No preview errors but not passing....

structs.swift 
struct Tag {
  let name: String
}
struct Post {
  let title: String
  let author: String
  let 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"))

Your function's return is incorrect. You usually use self to initialize properties, not in functions or methods. You only need to put the name of the property.

Here's how it should be.

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

Ah, I tried that before, should've said that. same result.... OH! "tag.name" the period there! waaah!! :))

Thank you again, you're kinda awesome!

EDIT: The 'self' there actually passes, but I know what you mean. ;) (funny how this code ch. was already marked as completed by the sys though...)

Totally weird. Didn't know that it passed with the self notation! The code must be all perfect and match the answer almost exactly to pass through. That sucks sometimes, because Xcode says all is ok, but Teamtree doesn't accept the code.

Nils Sens Maria Angelica Dadalt It is true, the treehouse code editor is very strict in terms of the accepting the answers.
