ios – The way to separate tableview header and cellForRowAt from identical json in swift

I need to show countrycode as header of desk view and after click on on header venue ought to show. I had tried however I am unable to realize output as anticipated.

That is my json :

{
  "conferences": [
    {
      "meetingId": 31389393,
      "name": "Ludlow 20th Apr",
      "openDate": "2022-04-20T12:00:00+00:00",
      "venue": "Ludlow",
      "eventTypeId": 7,
      "countryCode": "GB",
      "meetingGoing": "Good"
    },
    {
      "meetingId": 31389469,
      "name": "Catterick 20th Apr",
      "openDate": "2022-04-20T12:40:00+00:00",
      "venue": "Catterick",
      "eventTypeId": 7,
      "countryCode": "GB",
      "meetingGoing": "Good (Good to Soft in places)"
    },
    {
      "meetingId": 31389416,
      "name": "Perth 20th Apr",
      "openDate": "2022-04-20T12:50:00+00:00",
      "venue": "Perth",
      "eventTypeId": 7,
      "countryCode": "GB",
      "meetingGoing": "Good to Soft (Good in places)"
    },
    {
      "meetingId": 31389532,
      "name": "Lingfield 20th Apr",
      "openDate": "2022-04-20T15:15:00+00:00",
      "venue": "Lingfield",
      "eventTypeId": 7,
      "countryCode": "GB",
      "meetingGoing": "Standard"
    },
    {
      "meetingId": 31389447,
      "name": "Salisbury 20th Apr",
      "openDate": "2022-04-20T15:25:00+00:00",

      "eventTypeId": 7,
      "countryCode": "GB",

    }
  ]
}

   let obj = Racing(countryCode: cc ?? "", venue: venue)
   self.todayRacingArray.append(obj)
}
self.otherSportsTableView.reloadData()

func numberOfSections(in tableView: UITableView) -> Int {
    return self.todayRacingArray.rely
}
