Do you use the swipe to type feature on your phone?
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.
Ever since Swype came out I've been using it. I tried to use swiftkey and gboard when swype stopped updating. But I went back to Swype even if it is deprecated it just feels better to me
