Yeah - "Clean" in this context is the reversal of a "Build". It's intended to remove your build products. You should very rarely have a reason to Clean.

A project can contain many targets. It is often times convenient to allow all targets in the project share some set of build settings. One way to achieve that goal is to set the build settings on the project, allowing them to be inherited by all the targets. It is, for this reason, expected that the custom build settings that you find on your project to be different from the custom build settings that you find on the targets in your project. It's not uncommon for Xcode users to get tripped up on this though.
