Question:
Was trying to cut down on binary size. If I'm only going to release on ios 8 and above, can I only include the arm libraries in the final build?
Looking here: http://en.wikipedia.org/wiki/List_of_iOS_devices
I think the answer is that the hardware model iPhone 4s and up are capable of running the iOS 8 operating system. If you were only going to support the models iPhone 5s and up, then it seems you could only include the arm64 library in the final build.
