Xcode 5.1 64-bit simulator did not run

[udibr]

When trying to run a 64-bit simulator I got error message:
No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=i386).

I fixed this problem by doing:
Project Target > Build Settings > Architectures
and make
Build Active Architecture Only = NO

but then I got "Undefined symbols for architecture i386" for libevernote-sdk-ios.a

I fixed this problem by repeating the above procedure for the evernote-sdk-ios project
