Building a multiarch app with Xcode

Question

I am trying to get so called fat binary with iOS app. So, I defined in my Xcode:

Architectures : Standard (arm64 armv7)
Build Active Architecture Only : No
Valid Architecures: arm64 armv7

And build process succeeded. The output file is app.ipa. But, I have a problem with compability on 32 bit devices. So, I investigate to app.ipa: lipo -info app.ipa. Actually, it says that is is non-fat arm64 file.

But why? After all, I configured correctly.

When I create empty project and set conifg as above it works.

How to resolve it?
