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)"
}
