Juli Clover, MacRumors:
With the iPhone 11, 11 Pro, and 11 Pro Max, Apple did away with 3D Touch across its entire iPhone lineup, replacing the former 3D Touch feature with Haptic Touch.
In this guide, we’ll go over everything you need to know about Haptic Touch and how it differs from the 3D Touch feature that’s been available since the iPhone 6s.
If you are confused about Haptic Touch, or want to learn about the settings, read the article. Well done.
And personally, I am very happy with this change. 3D Touch and Haptic Touch had too much overlap, confusing discoverability.
