Do PWA push notifications already work on iOS browsers?
No
Nope, and it wasn't on the list of WebKit goals that was on the front page this week.
And thank god for that. Such a bad idea imo. I only get those from annoying sites, like a dark pattern. Ugh.
Browsers ask permission first. Also I don't see how having to install an app is any better other than being better for devs to track you.
I might install one app per hundred sites that annoyingly prompt for notification permissions, though.
And I install one app per hundred sites that annoyingly prompt me to install their app so they can give me push notifications (or, worse, a working website because they didn't bother even trying to build their product as a website anymore because of the lack of push notifications; it is ridiculous). So? The site is going to prompt me either way. This argument makes no sense: of course I would rather get promoted for the one feature I don't want to give them instead of an attempt to upsell me on an entirely different experience after being served crippled content... that is a total no brainer.
