Note that if anyone truly misses these operators, you can add them back with a few lines of code. Swift has extensive support for custom operators, and if ++ and -- disappear as built-in operators, you can just implement them as custom operators.
I see a lot of people complaining that they like ++ and -- who may not realize that they can still have it if they want it. I get that there are legitimate questions over whether it's wise for the community and such, but for your own work, you can still have it if you want it.
