When Apple introduced the concept of an iPhone without a Home button, it brought with it a new concept for those who switch apps frequently. The Home bar—the elongated pill-like shape at the bottom of the screen that you swipe up to return Home—also lets you switch quickly between recent apps.
If you’re an 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 that Home bar to the right to switch to your previously-used app. Swipe right again to keep going through recent apps.
Not only is this method of multitasking quicker, but it also means that you are much less likely to accidentally return to the Home screen when trying to invoke the multitasking view.
