Without a Home button, you no longer double-tap, but you do still rely on the bottom section of the device. Apple has also introduced a feature to the iPhone X that's been present on iPads for a while: fast app switching, allowing you to swipe your finger along the bottom of your iPhone X and quickly switch between apps.
Fast app switching is a very convenient way to quickly switch back and forth between your recent apps.
1. Touch your finger to the gesture area at the bottom of the screen, either while on your Home screen or in an app.
2. Swipe right or left to switch back and forth between apps.

2. Swipe up and hold your finger in place for a moment until the card-like multitasking interface appears.
3. Tap and hold on the app you want to quit until the red circle with the "-" symbol appears in the top left corner of the app.
4. Flick the app up.
5. Alternatively, tap the red circle
