More of a procedural question than anything else for which I can not find a definitive answer. In didUpdateFocus(in:with), is the call to super necessary?
The documentation states:
"After the focus is updated to a new view, the focus engine calls this method on all focus environments that contain either the previously focused view, the next focused view, or both, in ascending order. You should override this method to update your app’s state in response to changes in focus."
However it does not make mention of super whereas viewWillAppear: explicitly calls out that the call to super is necessary. So, are we to infer that because it's not explicitly called out, it's not a requirement? Even in WWDC transcripts and videos there isn't any consistency.
