This feels like an enormously loaded set of expectations you are bringing here. If one in one hundred thousand people could reproduce this answer I'd be surprised.

This question of immediacy feels like it applies to any form control. I don't see how the slider is in any way clearer or more obviously immediate.

IMO this just comes down to Apple having switched to mainly using sliders, and wanting that to be a look people can use. And it so happens that Apple doesn't have "save" or "submit" or "done" on any of their forms: on Apple it so happens that almost all their form controls are live. But these are two separate decisions, aesthetic and function, and wanting to couple them is just forcing your prejudice, and there's not any actual reason cause or substance for it.

I have the same expectation - that's what a switch does, both in real life, and on devics. You toggle it, the thing happens. So I don't think this is 1 in 100,000.

For what it’s worth, I have the same expectation and have been applying it to forms since IOS 3 or 4.

If we’re going to have a switch-looking thing, it’s because it brings some skeuomorphic affordance with it: I think “off/on with immediate effect” seems like exactly the thing it should bring to differentiate from a checkbox.

Having a weird design language expressly for immediate-effect entities is absurd & dumb. There's other context we should be using to set expectations, rather than creating parallel systems that do the same thing but through gentle skeuomorphisms imply something. Currently we have checkboxes and checkboxes alone as distinct, but it feels like this line of logic should be extended further if this is the implication.

I think it's still 1 in 100,000 in any broad sense of people, not just Apple-fans on HN. Especially not folks who are already reading the thread.
