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 use it all the time, but I’ve recently got a new phone and it’s taking a while for the autocorrect to get used to my swiping, so it has a fair few mistakes currently
