Since iOS 17, I have had no problems with text input. It feels better than anything that preceded it which I used on Apple or other platforms. That is true for swiping or typing and in either of the two languages I use. I’m actually blown away by how good it is sometime, correcting words based on the clause around it.

I also have an S10 Lite that I keep up to date. The native input there is okay, but not nearly as accurate.
