The tag variable within the Post class contains an instance of the Tag class. So when you refer to tag in the string you are actually printing out the tag instance in its entirety, not just the name property. To print out just the name you have to use tag.name instead. Like this:

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