I'm making an iPhone/iPad app that includes a library that's only compiled for architecture armv7. That includes all iOS devices prior to the iPad Air, iPhone 5C/S and iPad Mini gen 2. Those devices have a armv8-a architecture. If I compile my app for armv7 (with Valid Architectures set to "armv7"), will the app run on the armv8 devices too? And what about 64-bit?
It would make sense that apps from the iOS 6 era, will still run on those newer devices. I know that for instance, when compiling for armv7, your app will still run on the iPhone 5's armv7 because it's a subset.
Your help is greatly appreciated!

Yes, theorically you could even compile against armv6 and it will work on all the future devices.
A nice infograpich about mobile Apple architectures
Btw "armv8" is called arm64
