XCode compiles entire project each time I run
On a new project I have started, XCode has decided that it will compile every file in the project every time I run it, rather than just compiling files that change (and files dependent on those). As there are getting to be more and more files in the project, this becomes a bigger and bigger burden in both time and battery life.

It is possible that I have changed a setting somewhere that affected this; or, maybe not. What are some project settings that I should be looking at?
