I'm using a DateTimePicker that contains a Start Date and Time. Although the time updates properly, the date does not update based on the scrollview. Any idea what I can change to make it work?

Here's the code:

class DateTimePicker: NSObject, UIPickerViewDelegate, UIPickerViewDataSource {
    
  // Reference from https://stackoverflow.com/questions/40878547/is-it-possible-to-have-uidatepicker-work-with-start-and-end-time
    
    var didSelectDates: ((_ start: Date) -> Void)?
      
      private lazy var pickerView: UIPickerView = {
        let pickerView = UIPickerView()
        pickerView.delegate = self
        pickerView.dataSource = self
        pickerView.backgroundColor = .white
        return pickerView
      }()
      
      private var days = [Date]()
      private var startTimes = [Date]()
//      private var endTimes = [Date]()
      
      let dayFormatter = DateFormatter()
      let timeFormatter = DateFormatter()
      
      var inputView: UIView {
        return pickerView
      }
      
      func setup() {
        dayFormatter.dateFormat = "EE d MMM"
        timeFormatter.timeStyle = .short
        days = setDays()
        startTimes = setStartTimes()
//        endTimes = setEndTimes()
      }
      
      // MARK: - UIPickerViewDelegate & DateSource
      
      func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 2
      }
      
      func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        switch component {
        case 0:
          return days.count
        case 1:
          return startTimes.count
//        case 2:
//          return endTimes.count
        default:
          return 0
        }
      }
      
      func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {
        var label: UILabel
        
        if let view = view as? UILabel {
          label = view
        } else {
          label = UILabel()
        }
        
        label.textColor = .black
        label.textAlignment = .center
        label.font = UIFont.systemFont(ofSize: 15)
        
        var text = ""
        
        switch component {
        case 0:
          text = getDayString(from: days[row])
        case 1:
          text = getTimeString(from: startTimes[row])
//        case 2:
//          text = getTimeString(from: endTimes[row])

        }

In the main MessagesViewController, I have :

    private lazy var dateTimePicker: DateTimePicker = {
        let picker = DateTimePicker()
        picker.setup()
        picker.didSelectDates = {[weak self](startDate) in
            let text = Date.buildTimeRangeString(startDate: startDate)
            self?.actualDate = startDate
            self?.label.text = text
            dateText = text
        }
        return picker
    }()
