16 years in and iOS still doesn't have this feature that MacOS (née Mac OS X) has had since it launched 22 years ago: “Learn Spelling”.
@gruber I must admit that I had my chance long ago. I had a hand in on adding spellcheck, the red squiggle, and the menu system to iOS, and of course, the text system too. Other things took priority and then I moved onto other projects. Sorry!
@kocienda Ugh. This one really hurts, Ken.
@gruber @kocienda The really depressing thing is that Learn Spelling would probably break all the machine learning bullshit (or at least be hard to work side-by-side), so it’s unlikely to happen now.
