Discussion

The task view controller uses this property to get the results for the step, and to collate them into the task result.

The current step result and any subsidiary results representing data collected so far are available in this property. You can detect significant changes to the result, such as when the user enters a new answer, using the stepViewControllerResultDidChange: delegate callback.

Subclasses must use this property to return the current results. Subclasses may call super to obtain a clean, empty result object appropriate for the step, to which they can attach appropriate child results.

The implementations of this method in the ResearchKit framework currently create a new result object on every call, so do not call this method unless it is actually necessary.
