36.10 Summary

This chapter has explored the implementation of animation when changes are made to the appearance of a view. In the case of implicit animation, changes to a view caused by modifiers can be animated through the application of the animated() modifier. Explicit animation allows only specified properties of a view to be animated in response to appearance changes. Animation may also be applied to state property bindings such that any view changes that occur as a result of that state value changing will be animated.

A transition occurs when a view is inserted into, or removed from, a layout. SwiftUI provides several options for animating these transitions including fading, scaling and sliding. SwiftUI also provides the ability to both combine transitions and define asymmetric transitions where different animation effects are used for insertion and removal of a view.
