How to leave TODOs for yourself as part of Xcode4?

The one thing i like about Eclipse is that it lets one leave annotations like //TODO:, which IDE highlights and draws your attention to.

Is there anything like this available for Xcode?

Ultimately, i'd like to mark things as to be comple开发者_开发知识库ted without fear of forgetting to revisit this code later. Searching for this is fine, but i can't help but think there has got to be something better.

Please let me know.

// FIXME: foo
// TODO: bar

Works the same.
In addition, these show up in the drop-down list of method names, so you can see and jump right to the areas that need more work.
