With Apple's new requirement to have a 64 bit build support, apps executable are getting bigger.
After several attempt to reduce the final build size to something < 100mb I was wondering if it was possible to drop 32 bit support and only support 64bit.
Building an app for 64bit only works fine but the submission process seems to prevent such behavior.
Adding this non-documented UIRequiredDeviceCapabilities does not change anything as the error becomes the following
I checked that there is no mention of armv7 or armv7s in my architectures settings
Yet people on the Unity forum seems to say that it's possible based on a similar conversation on Apple's Forum
iOS 8 (and iOS 9) are supported on 32 bit devices, such as the iPhone4s so you must include armv7 in your builds. You will need to wait for app thining in iOS 9 to reduce your bundle size.
