When trying to archive an app for an Ad Hoc release, I am getting the following warning:
iPhone/iPod Touch: application executable contains unsupported archite
Go to Project ---> Build Settings and scroll down to the Architecture setting.
You will probably see the value $(ARCHS_STANDARD_32_BIT) listed under Architecture.
If so, double-click $(ARCHS_STANDARD_32_BIT), select it, and click the minus button to get rid of it. Then click the plus button and write armv7 and press Enter.
You have now removed armv7s, which was unsupported. Try it again and things should be good.
