Check out the accompanying blog post for more details: Building Fluid Interfaces
Background
At WWDC 2018, Apple designers gave a talk titled "Designing Fluid Interfaces", explaining the design theory behind the gesture-based interface of iPhone X. (The presentation is available here: Designing Fluid Interfaces)
It was an outstanding talk, inspiring designers and developers to think about animated interfaces in a new way. While some technical guidance was provided, most code-level implementation details were ommitted.
The goal with this project is to bridge the gap between inspiration and implementation.
Installation
Download or clone the repo and open the FluidInterfaces.xcodeproj file with Xcode.

Rubberbanding
A demo showing how to implement rubberbanding.
Acceleration Pausing
A demo of using a gesture's acceleration to quickly detect when the user's motion has paused.
Rewarding Momentum
A drawer with an open and closed state which has bounciness dependent on the velocity of the gesture.
FaceTime PiP
