How to exclude iPod touch 4th generation for the application

Question

I want to release an application for the following devices

• iPad 2 or higher
• iPhone 4 or higher
• iPod 5 (or higher)

The problem is that I can’t find something to rule out 4th generation iPod touch, but it doesn’t have enough RAM to run the application, so it crashes every time. Does anyone have experience with this problem?

You can exclude devices only based on the functions listed here:

I am not aware of any feature that will save you from iPod touch 4th generation, I believe that your only option is to optimize it even more.
