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.
