Most of the time, SwiftUI will do its Layout Magic and life will be wonderful. However, there are times (many times), when we require more control over the layout of our custom views. For these moments, we have several tools. The first one we are going to explore is GeometryReader.
In this article we are going to dive into some advanced techniques to create SwiftUI animations. I will talk extensively about the Animatable protocol, its trusty companion animatableData, the powerful and often ignored GeometryEffect and the completely overlooked but almighty AnimatableModifier protocol.
