Make app Ipad only?

Is there something I have to do within Xcode in order to make my app Ipad only? I cant find a straight answer for this. Thanks in advance.

Why not just change the target device in Unity?

Yea that is what I originally thought was all I had to do, but I went to submit the app to iTunes Connect and it is still requiring me to submit iphone and ipod screenshots. Is that just how it is even if your target device is Ipad only?
