Feedback Publishing iOS app with iPhones / iPad having Ram more than 2 GB

Hello,

I am working on a iPhone / iPad app, which requires around 1-1.2 GB as RAM. My app runs fine over devices which have Ram more than 2 GB.

I want to restrict the users to not to download the app who has iPhone 6 or lower or having iPad less than 2 GB Ram.

Is there any option where I can choose hardware specification while publishing app, so users who have 1 GB ram phones, don't get an option to download.

I got similar option in Android while publishing, Now android users having less Ram can't download my Android App, but for iOS I am not able to achieve it.

It will be great if someone can assist me with the solution.

Regards,
Paramjot Singh
