Since the iPhone X lacks a Home button, how do you now switch between open apps? You used to press twice for the app switcher, now you’ll need to switch apps in a new way. To bring up the app switcher, swipe up from the bottom of the screen to about halfway, and then pause until the app thumbnails appear. The key is the pause. Then you can scroll through your launched apps by swiping horizontally and switch to an app by tapping its thumbnail. While in the app switcher, you can also force-quit a frozen app: press a thumbnail to get a red minus button and tap that button. Alternatively, you can skip the app switcher entirely. Just swipe right on the very bottom of the screen to switch to the previous app. Swiping left switches to the next app.
