问题
Just noticed the Simulator for the devices that do not run arm64 (so iPhone4/5, iPad 2, which should be running i386 simulator) runs x86_64 in the simulator for release mode now in Xcode 6 by default. To clarify: Debug mode still calls i386 for these simulator targets... so weird.
Noted in the build log:
clang++ -arch x86_64
This is a bit of an issue testing for older projects that only compiled vs the old i386/i686 architecture for release mode.
Anyone have any idea how to make it run in i386 for release as well?
