You may need to blow away your CMakeCache.txt and re-run CMake from scratch to reconfigure your build directory when changing xcodes. The CMake build system ought to use xcrun to sniff out the system compiler paths, but I believe it only does so during configuration time, and won't pick up changes made after the fact. -Joe _______________________________________________ swift-dev mailing list swift-dev@swift.org https://lists.swift.org/mailman/listinfo/swift-dev
