Instead of eliminating the feature, they created gestures that trigger the multitasking screen on newer premium devices.
With the iPhone X, X S, X S Max, and X R, Apple thought about this and came up with an elegant solution. But wait, what about the other features of the Home button? How will you even access the app switcher? At first, you worried about the lack of Touch ID, but Apple assured you that Face ID is an adequate alternative. You imagined watching videos and enjoying HD content on its gorgeous OLED or Liquid Retina screen. So you saw the new iPhones with their bezel-less designs and fell in love.
