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 swipe and tap to type. It really depends on what I’m doing. If I’m typing one handed, swiping is really nice and super fast. I’ll also swipe to type if my phone is on the table and I’m only typing with one finger. If I’m using both hands, I will generally tap to type.
Edit to add I used SwiftKeys on Android
