By now, you've probably heard that the iPhone XR features a new technology called Haptic Touch instead of the usual 3D Touch.

Haptic Touch is simply a marketing name for a long press combined with haptic feedback from the Taptic Engine. The feature is a substitute for 3D Touch, which Apple wasn't able to include on the iPhone XR in order to achieve a nearly edge-to-edge LCD screen, a remarkable engineering feat.

The biggest downfall with Haptic Touch is that it currently works in only a few places, such as the flashlight and camera shortcuts on the lock screen, and in Control Center to pop open additional toggles and menus. Fortunately, that won't be the case forever, according to The Verge's Nilay Patel.

From Patel's iPhone XR review, emphasis ours:

Haptic Touch does not have equivalents to everything 3D Touch can do, however — I missed previewing links in Safari and Twitter quite a bit. Apple told me it's working to bring it to more places in iOS over time, but that it's going slow to make sure the implementation is right.

Apple did not provide a timeframe, but it's safe to assume that additional Haptic Touch gestures will be added in future software updates.

It'll be interesting to see where Apple expands Haptic Touch across iOS, as the feature can only be implemented for actions that don't already rely on a long press. For example, long-pressing on an app icon on the home screen enables "wiggle mode," allowing apps to be deleted or rearranged on the home screen.

For that reason, Haptic Touch does not work with Quick Actions when you long press on an app icon on the iPhone XR home screen. Haptic Touch also doesn't support Peek and Pop for previewing content such as links and messages.

Apple already works around the lack of 3D Touch for keyboard trackpad mode. In iOS 12, users can simply tap and hold the space bar to enter the trackpad mode, which allows for easier movement of the cursor within text fields. This user interface change was more than likely inspired by the iPhone XR.

A few months ago, Barclays analysts said it is "widely understood" among Apple's supply chain partners that all 2019 iPhones will lack 3D Touch. If accurate, Apple's plans to expand Haptic Touch may go beyond software. For now, the pressure-sensitive feature lives on with the iPhone XS and iPhone XS Max.
