Tells your app to peform any necessary logic after constraints are applied.

```
func didApplyConstraints()
```

## Discussion

Do not call this method directly; it is called exactly once per frame, so long as the scene is presented in a view and is not paused. By default, this method does nothing. Your scene subclass should override this method and perform any necessary updates to the scene.
