I'm developing an iOS game using ARKit. The game concept only works if 6DOF tracking is available, which means that an A9 chip or newer is available.
I don't want users to install the game on older devices like an iPhone 6 - on these devices ARKit would fallback to 3DOF tracking, which doesn't make sense for my game concept (I need translation tracking).
How can I enforce this restriction, that the app can only be installed on devices supporting 6DOF (which, to my knowledge is equivalent to iPhone 6S or newer or iPad Pro or newer, or A9 or newer)?
I checked the iOS Device Compatibility Documentation and the UIRequiredDeviceCapabilities Reference but did not find anything suitable.
