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 run LineageOS on my phone so I sadly don’t have that feature. I found it was easier for me to quickly reply to texts but I would still fall back to typing with 2 thumbs (as I am now) and now that I have no swype-esque keyboard I think I may be faster without it.
