xcode - Why is clang recompiling all C++ files including a header file if the recent change does not impact most of them? -


i have constants header file included of source files. if change constant in there used ~2 source files, clang still recompiling ~300 source files include header file.

is there way recompile source files influenced change made without having split constants file many tiny parts? speed compilation process after small changes.

since build system , environment seems matter: i'm using xcode 8.3.3 on osx, compiling c++ code ios.
