Xcode 4 variable summaries in debugger

In Xcode 3, when viewing variables with the debugger, there was a "Summary" column, shown in this image. You could edit what appeared there, so you could preview all kinds of data types. In Xcode 4, I can't find similar functionality. I've found I can right-click the variables and choose "Edit Summary Format...", but though I can edit it like in Xcode 3, the actual result doesn't seem to show up anywhere! This demonstrates my problem:

As you can see, there's no summary column. How can开发者_开发问答 I actually see the result of the summary in Xcode 4?

Eh, I was having lots of issues with Xcode, so I just ended up doing a clean install. It seems to have fixed the issues. Oh well.
