I've upgraded to xcode 7.3, and all of a sudden my C++ project which used to only compile if changes had been made to a file now recompiles on every run. Even if when I immediately re-run my app without changing any files xcode insists on re-compiling all the files in my project + the files in the 2 related library projects before running.
I tried the suggestions here: https://forums.developer.apple.com/thread/44406 to no effect. I recognize that there's a "Perform Action => Run Without Building" under Product, but I feel like I used be able to just select "Run" and xcode was smart enough to figure out whether it needed to re-build or not. Have I done something wrong, or am I going crazy?
