Simple animations in SwiftUI are refreshingly easy. However, some animations are deceptively tricky, as we don't have access to completion handlers. Animation is entirely state-based, so if we have an animation where an item needs to move and return to its original state, we need to take a different approach. In this episode we will model a bounce animation using a simple sine function, feeding in the time value t using SwiftUI's linear animation interpolation.

This episode uses Xcode 12-beta1, Ios 14.0-beta1.
