With all due respect, this is garbage. Even if I get out my ancient iPhone 7+ I do not see or experience the problem issues the writer describes. Auto-suggestions can be funky, but so can Google's. BTW, I have carried two phones, both an iPhone and an Android, for at least 6 years. Before that I was a Android-only user. I have zero lag when typing, my current iPhone is a 13 Pro Max.
What the writer also doesn't seem to get is auto-suggestions and auto-correct are directly a part of the keyboard, but the OS itself accessible by other apps as well. Furthermore, the keyboard learns from user's input. I know he said he'd tried phones that he didn't sign into his Apple account, but I find it very hard to believe that "Problem" is suggested as "Problem's" when on ALL the iPhones I tested this morning I was offered "Problem" (as the default), Problems, and Problematic NOT Problem's. As for Ebfore, I was offered the choice to stay with that OR Before or E foreign. For I'll and I've, he's again not talking about an actual issue. Here are actual screenshots my results (interestingly enough, the writer didn't provide ANY screenshots of his claims):

If iOS's keyboard was really this bad, you'd better bet that the 50%+ of US users, many of whom are converts from Android, would be up in arms about it. Since users whine when they lose a few minutes of battery life for a couple days after an upgrade while the OS re-indexes everything, you know good and well they'd be screaming about the keyboard. In the end, this article reeks a seriously slow news day and the writer needed to get some clickbait out there to justify his paycheck.
