When making charts accessible, sometimes you may have just too many data points for the user to have to go one by one through all of them. In those cases, you can create accessibility elements that represent meaningful chunks of the graph.

Apple asks us to consider the combine behavior, before using ignore, for .accessibilityElement(children: ). And for good reason, if combine works, and later on you decide to change the UI, the accessibility attributes will be updated for you.
You can create your own accessibility elements from scratch. One use-case for doing that is when you do some custom drawing instead of building your UI using or relying on UIKit components. A circular progress bar, could be an example.
A common example where you need to manually configure the button accessibility trait is for some table/collection view cells. These tend to be “buttons” that perform an action, like playing music, or bring the user to a different screen.
