I'm in the process of submitting an app to the App Store and am preparing screenshots for various display sizes. I noticed that there's an option for a 13'' display, which corresponds to the new iPad Air. However, I can't find a simulator for the 13'' iPad Air in my XCode. Is it mandatory to upload screenshots for this size, or can I omit them? Additionally, how can I download the simulator for the new iPad Air?
Thanks!
