application executable is missing a required architecture armv6

Question

I am using xCode 4.2 and trying to deploy my application. I am failing the validation with the following error message:

application executable is missing a          


        

Answer 1

I stumble upon this question when looking for a solution to the warning:

warning: iPad: application executable is missing a required architecture.
At least one of the following architecture(s) must be present: armv7 (-19033)
Unable to validate your application. - (null)

Other answers did not solve my problem, then I realized I changed a value of CFBundleExecutable. When I returned to the old value everything went smoothly again.

I'm not sure what is a direct cause of that warning but at least I can distribute Ad Hoc builds again.
