When I'm updating my first iOS app , I have 2 problems validating them,
*iPhone/iPod Touch:application executable is missing a required architecture.
At least one of the following architecture(s) must be present: armv7
*Unable to extract entitlements from application: (null)
The Info.plist and build settings are all the defaults, the only thing I changed is the code signing Identity debug and release to my distribution provisioning profile, with the app ID and Bundle Id identically.
This happened to me when i had my iphone 5 connected and built my archive. when i disconnected my iPhone and built my archive, it went through fine.
