'no member named x in namespace' for all example files

I’m trying to run example files from OF 9.3 using XCode 7.3 and get a large number of error messages of the type ‘no member named x in namespace’, for a variety of namespaces (std, std_1, global), and in a variety of files (Ascii.h, memory, algorithm, String.h, etc.). I’ll be grateful for any tips to help solve this problem.


Sorry not to have received any replies for this, but I can say that, having now downloaded the nightly build, everything seems to work fine.
