Hi Guys, I don't have an y explanation for this.. Works fine on iPhone 5, go to try iPhone 4S and this happens. There are no device requirements, and every architecture string I see is armv7 and armv7s. If I turn off "Build for active architecture only", then it does compile (I guess for armv7s), and halts at the last minute and asks for me to select a device with a valid architecture. Any ideas there? Another project I have behaves properly when I use the BFAAO setting.
