Looks like iOS 12 has revamped the way iPhone X users will clear apps from multitasking. Currently, iPhone X users need to swipe up from the bottom, tap and hold for the red ‘delete’ icon, then swipe apps away to remove them.
But in iOS 12, all you have to do now is swipe up to multitasking, then just swipe apps away, which looks and feels more natural and is consistent across all iPhones.
Also, if FaceiD fails, you can swipe up to try again from the passcode page.
