**Building Settings:**

**Valid Architectures:** armv7 armv7s arm64
1. Clean and build your app with the iPhone connected

Architectures: arm7,arm64

"Build Active Architecture Only - NO (specially... if your connected device is not arm64 compatible)"
My iPad is not 64 bit. Put in NO for Build Active Architecture and my submission worked! |

] | As Tony wrote, it's important to have in both lines those settings.
Since my (and obviously your) project was created yet before arm64 was added to standard, it is not reflected in "Valid Architectures" even if it is *shown* as Standard.
What I did:
* I went to Project (vs. Target) configuration
* *Typed* "arm64" in ... | Please check Build Active Architecture option. Set it to NO.
It works for me. |
