Hm, I'm not sure what Apple's message is here. That the iPhone is too small for two-finger gestures? As someone said, early 9.0 betas allowed swipe selection on the iPhone as well as on the iPad, but this was removed later on. The iPad still does it using two-finger swipe, and now the iPhone 6s does it… how? With a light press on the keyboard, then single-finger gestures, I assume?
