Updated Xcode to latest version and now getting a strange compiler error when I try to compile my existing project. I assume this is some build setting which needs changing but can't work out where.
Apple LLVM Compiler 4.1 error
clang: error: the clang compiler does not support '-fobjc-abi-version=0'
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1
What does this mean?
