You know absolutely nothing about ios process management, apparently.
That doesn't dispute what I said. Just look at the facts.
Switching tabs with other apps shown as active in the app switcher: tabs reload.
Killing all those other apps (that apple claims are doing nothing and using no ram or other resources) and then going back to safari and switching tabs: tabs appear instantly, no reload.
The point in question is whether there is benefit to quitting apps. Regardless of what anyone "knows about ios process management", the benefit of quitting apps is right there to see in front of our very eyes.
If you have an actual argument to dispute that, I'd love to hear it.
