Attached video shows issue of partial rebuilds. Here is the description of performed steps.
- Open app in xcode and build it
- Make sure it performs as expected
- Swap order of virtual methods in the AbstractClass.h
- Change something in ConcreteClass.cpp to force it's compilation
- Run app again
- Observe that main.cpp is not recompiled even tho it includes AbstractClass.h indirectly.
- Run application and observe that wrong virtual method is called.
