Apple’s new iPhone XR doesn’t include 3D Touch. App developers already didn’t use 3D Touch, but now they really won’t use it. Apple will have to design the iPhone operating system not to rely on 3D Touch so much.
Sure, the new iPhone XS and iPhone XS Max still have 3D Touch. But we wouldn’t be surprised to see it vanish from future iPhones. App developers can no longer rely on it.
