Is this how most people type on mobile these days, drawing lines all over a keyboard instead of tapping the individual keys? I’ve never had an iPhone so I don’t even know if they can do this natively, but I know you can switch keyboards at least, so it should still be an option if not.
I tend to swipe (on Android btw) whenever I only have one hand available, and type when I have both. It works really well and barely ever comes up with a wrong with.
