I also filed a bug on this and got a reply stating that this is intentional. If you want to build for armv7s you have to add the architecture manually. I have now idea why this change was made. I'll update this if I get additional information.

Update from the dev forums:

The reason for including armv7s would be marginal backward compatibility. Butthe general differences between armv7 and armv7s instruction sets are minor. So if you choose not to include armv7s, the targeted armv7 machine code still runs fine on 32 bit A6 devices, and hardly one will notice performance gap.

From @vladof's post on the Apple forum, if you need to include armv7s support you need to add it manually. You can do so by changing the architecture setting to be like this:

You may want to do this if you're building a library and users are expecting the armv7s slice to be available.

Please note that this answer was made at very early stage of the quest, has been unchecked for answer when Xcode 6.0 GM came out. This is meant only for tracking, refer to other answers for detailed information.

This appears to be a bug of Xcode 6 Beta, according tothis thread on Apple forum. A bug has been opened.
