Building surveys

Now that you have learned about the results of tasks from the previous section, we can modify the Softwareitis project to incorporate processing of the task results. In the TableViewController.swift file, let's update the rows data structure to include the reference for processResultsMethod: as shown in the following:

//Array of dictionaries. Each dictionary contains [ rowTitle : (didSelectRowMethod, processResultsMethod) ] var rows : [ [String : ( didSelectRowMethod:()->(), processResultsMethod:(ORKTaskResult?)->()  )] ] = []

Update the ORKTaskViewControllerDelegate method taskViewController(taskViewController:, didFinishWithReason:, error:) in TableViewController to call processResultsMethod, as shown in the following:

func taskViewController(taskViewController: ORKTaskViewController, didFinishWithReason reason: ORKTaskViewControllerFinishReason, error: NSError?)
{
    if let indexPath = tappedIndexPath
    {
        //1
        let rowDict = rows[indexPath.row...
