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 used to do it when phones had smaller touch screens. Now I type with both thumbs. That is a lot faster than swiping with one finger
A lot of keyboards have a one-hand mode that really helped and kept me using the swipe typing even as the screens kept getting bigger.
