This seems to be a new option in newer XCode - instead of \"armv6 armv7\" under Valid architectures I now see \"armv7 armv7s\". What is armv7s and do I need to build for it
armv7s is the architecture of the A6 processor in the iPhone 5. And yes, you need to include this as well. With the latest version of Xcode, support for armv6 is dropped.
