Logic of Peek and Pop in 3D Touch

TL, DR

In 2015 Apple introduced 3D Touch. Before that there was already Force Touch on Apple Watch and MacBook Pro. Although both “touch” are techniques that make the touchscreen force-sensitive, 3D Touch on iPhone 6s / 7 are in a way of a higher dimension. 3D Touch is sensitive to continuous force changes, while Force Touch is discrete. With 3D Touch coming with new iOS devices, UIKit evolved too. A new way of interaction was introduced, which we’re going to talk about, that is, Peek and Pop.
