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.
This is the way! Also what a lot of others already commented, that it’s more smooth to use with one hand. For me it’s also nice to use, when it comes to switching languages. English is my second language and with swipe it feels like the autocorrect works pretty good, because it is more forgiving if you don’t know exactly how the word is actually written. A small idea about how the word is constructed is enough.
