Please note, this blog entry is from a previous course. You might want to check out the current one.

If a section has no items in it, there should be no header visible for that section.

… oops, didn’t notice that. We need to check if there are items to show:
[swift]
var tweet: Tweet? {

if media.count > 0 { … }

if urls.count > 0 { … }

if hashtags.count > 0 { … }

if users.count > 0 { … }

}
[/swift]

The complete code for task #4 is available on GitHub.
