The sample app has a table view, which will present a list of the available approaches. Selecting an approach will present a table view for the approach. The table view has 5 starting items, so it is clear when attempting to scroll whether the main thread is being interrupted by the long-running task. The long-running tasks will then create 50 more items in batches of 10 to display ...
