Why did 3D Touch fail?
The problem with 3D touch is that it contradicts all of those things and doesn't provide discoverability: there is no visual sign that an element is 3D touchable, so you need to guess what happens. I often find myself randomly force-touch elements on the screen without knowing what will happen.
Is force touch the same as 3D Touch?
Starting with the Apple Watch, Force Touch has been incorporated into many products within Apple's lineup. This notably includes MacBooks and the Magic Trackpad 2. The technology is known as 3D Touch on the iPhone models.
Is 3D Touch coming back?
Except for the trackpad on MacBooks, Apple has all but discontinued Force Touch (also known as 3D Touch) technology from its products. However, it seems that the company still has plans to somehow bring Force Touch back, as new patents reveal next-generation force sensors for Apple Watch, MacBook, and even iPhone.
