When Apple introduced the concept of iPhone without a home button, it brought with it a new concept for those who switch apps frequently. Home-So lets you switch quickly between recent apps.
If you're on iPhone XR, XS, or XS Max owner , you may already be familiar with a swipe up and pause gesture that opens the multitasking view. But if you just need to switch to a recently-used app, there's a quicker, more elegant way of doing so.
Swipe right back to keep going through recent apps.
The method of multitasking quicker, but it means that you are much less likely to accidentally return to the home screen when trying to invoke the multitasking view.
