How to exclude 4th-gen iPod touch for app

Question

I want to release an app 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 exclude the 4th-gen iPod touch but it doesn’t have enough RAM to run the app, so it crashes every time. Does anyone has experience with that problem?

You can only exclude devices based on features, listed here:

I am not aware of any feature that will eliminate an iPod touch 4th gen, I believe your only option is to optimise further.
