Do you guys remember how an app instantly closes midway during opening animation if we quickly press Home Button on iOS 10? But on iOS 11, it takes 1 second to complete the opening animation. Then 1 second it blocks any input or home button press and then closes. At first I thought that this is just OS optimisation issue. But when you take iPhone X into consideration which does not have a Home Button, things are clear. Apple wants to show the world that swipe up to close and return to home screen is faster. Planned Obsolesence exists. Hence proved.
