Answer 1

Try going into your Build directory and simply deleting everything.

For Xcode 3, the build directory is usually located inside your main project folder. For xcode 4, as discussed in this question, can be found, by default, in ~/Library/Developer/Xcode/DerivedData.

Also, be aware that you won't be able to clean a target if it's running inside the simulator (though it seems like that doesn't apply in this case.)
