I see where the confusion is coming from, and I’m still not sure what people mean with force close. It’s possible people even mean different things. There are 2 things and I’m not sure which most people are referring to
1. On an iPhone X, if I just swipe up quickly it closes the app the same as hitting the home button in older iPhones, but it is still open in the background. When I re-click on the app it comes up immediately, but does not have to reload or anything. It is then in the exact same screen in the app that it was when I swiped up.
2. Also iPhone X, if I am more specific about it and swipe up slower, for lack of the right term, it kind of grabs the page and makes it smaller, bringing up a set of smaller pages that are all of my open and running apps/pages, lined up kind of like a deck of cards on the screen. Then if I swipe it up from there it completely closes the app, and when I re-click the app it has to open again, which takes maybe 5-15 seconds and has to go through the fireworks again.
#2 is what I would think people mean when they say force close, but from the descriptions when people ask them I’m not really sure if it is or not.
on my one real day I didn’t have to do this so it didn’t make a difference, but due to my obsessive compulsiveness and type a-ness it bugs me when I don’t completely understand somethning, so when I also got the feeling others were confused I thought I would chime in and see if we can figure out which people are meaning when they say it!
