I don’t know what it’s doing, only how long it takes. My test was to build and 
then build again. In many cases I am only changing a source file far downstream 
in dependencies but I am rebuilding everything because I just push the build 
button in Xcode or type make.

I was not changing headers.

In many other cases skipping the entire build step based on file modification 
times is a great approach. I understand it might be hard to know which files 
need to be checked in a case like this so maybe that’s why we can’t apply the 
classic solution.
