I'm doing kernel development with Xcode. Since it is kernel development I keep my source on another computer and then copy the source changes to the computer under test for compile, build and test. But, unlike Windows Visual Studio, Xcode does not see that the files have changed outside of the editor. So far I have only been able to resolve this problem by quitting Xcode and restarting it. Is there a way to refresh Xcode after I do the copy?
