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. For example, if you want an animation to start after a certain number of seconds you should use the delay() modifier. You’ll find it a lot less effort to produce animations in your app. And so to do that, I define a single view with a single rotationEffect modifier and conditonalize its input based on our state.

The perspective distortion gives you an idea of … Now instead I'd really like that icon to rotate when it's flipped. If your object is straight and you rotate to 270 degrees (radians: pi + half of pi) it will rotate counter-clockwise because it's the smallest possible animation. So, if your object is straight and you rotate to 90 degrees (radians: half of pi), it will rotate clockwise. It can do what we can do in UIKit with less code, but that is not all.
