How to create basic animations, SwiftUI has built-in support for animations with its animation() modifier. SwiftUI will then figure out the rest. In other words, your layers and animations still take place in two dimensions, but you can rotate and position each element’s 2D plane in a 3D space like so: Shown above are two 2D images that are rotated in 3D space. If you really want to take your animations to the next level you need to incorporate some rotation . The implementation of this is fairly straight forward: The addition of compactMap() to RxSwift 5 lets us write less code and is more performant and memory efficient to boot, replacing three RxSwift operations with just one.
