| // A 30-minute hack to recreate the "iBeer" effect using SpriteKit, SwiftUI, and metaballs. | |
| // The effect is created by having hundreds of physics-enabled balls in a SpriteKit scene, | |
| // all drawing nothing. These balls are then read back out by SwiftUI in a TimelineView, and | |
| // drawn using blur and alpha threshold filters to make them appear to be a liquid. | |
| // The SpriteKit scene then has its gravity changed dynamically using the accelerometer, | |
| // meaning that the "liquid" splashes around as you tilt your phone. | |

A simple UIView that will move the contentView out of the way of the keyboard. It animates in sync with the keyboard and always works - even in a modal page sheet, a slide over, or any other context. Tested on iOS 12 and iOS 13.
