Saving results for ORKStepViewController Subclass

Hi,

I've subclassed ORKStepViewController and created UI on storyboard like ORKQuestionStepViewController to add a search option in tableView.

It's working fine. However, couldn't able to get the result object on back and forth.

I've overridden the result property.

   override var result: ORKStepResult? {
 
    let orkResult = super.result
    guard let identifier = step?.identifier else {return nil}
    let choiceResult = ORKChoiceQuestionResult(identifier: identifier)
    
    var choices: [Any] = []
    for choice in self.selectedChoices {
        choices.append(choice.value)
    }

    choiceResult.choiceAnswers = choices
    orkResult?.results = [choiceResult]
    return orkResult
} 

But when i go back and come to the view controller, i try to get the result object and it's nil

   func taskViewController(_ taskViewController: ORKTaskViewController, viewControllerFor step: ORKStep) -> ORKStepViewController? {
    
    print(step.identifier,"Identifier")
    if step.identifier == "newQuestionStep" {

        let textChoiceQuestionController = self.storyboard?.instantiateViewController(withIdentifier: "TextChoiceQuestionController") as! TextChoiceQuestionController
        textChoiceQuestionController.step = step
   
        return textChoiceQuestionController
    }

    return nil
}

Ongoing backward When I try to access the result here, I'm able to see my result ob subclass. However, when i click on next to the subclassed VC, I'm getting blank result object in the above delegate for the step identifier.

Start with the custom ORKStepViewController subclass and the taskViewController(_:viewControllerFor:) delegate shown in the issue. Trace how result is read and restored when navigating backward and forward, including the overridden result property and selectedChoices. Done means the subclassed controller retains and returns its ORKStepResult after revisiting the step.
