“XS” seemed to me like a blunder of a name. First off, I don’t know anyone who calls the X iPhones “ten” - they call them “x”. And so XS looks and sounds like “extra small.”

Without knowing anything about the X phones, I at first assumed that XR was the top of the line X phone. XR just... sounds like a better phone.

I think they resolved this with the 11 line.
