I’ve tried swiftkey in the past. It’s decent, but not as good as Swype was. I was using gboard almost exclusively until iOS integrated swiping in their default keyboard. When I first moved to iOS, you were still forced to use the default keyboard for any passwords/etc. I found that extremely frustrating, once it was built into the default keyboard I just started using it and have stuck with it. The default keyboard, at this point, isn’t awful but the predictive text/autocorrect is truly bad.

Back in the day with Swype, you could pick from multiple keyboard layouts. You could also customize colors and it built up a library of words you would use often. The autocorrect was actually a benefit. iOS will simply change your entire sentence if you aren’t careful. I find that I often have to reread my text input sometimes twice to confirm I’ve typed what I actually intended.
