I wanted to prevent Xcode from generating tons of warnings for third-party libraries I use and added -isystem flag to the "Other compiler flags". However, now build fails, giving me an error that my .pch file can not be found.

How does one affect the other? Can't wrap my head around this one.

  • You need to pass `-isystem` a directory, by itself it's useless, and it will end up not finding the includes since it's not a mind reader. The correct syntax is `-isystem directory` ... – l'L'l Jan 27 '17 at 10:51
