> What is vastly better on the X-series devices, though, is switching between your two or three most recent apps.
On devices with 3D Touch switching between 2 recent apps became easier once you learned this shortcut: just hard press the left edge of the screen, and depending on how far you drag it to the right, you can either go to the previous app or open the switcher (faster than double tapping the home button).
Just wanted to chime in on this: it doesn’t matter how far you drag it to the right, but how “deep” you press: after pressing once, give it another, deeper press and the app switcher will appear.
