回答1:

Yes you have to create three custom cell, for crousal either use third party or a collection view inside tableview cell.

for eg:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
  let cellIncomming = tableView.dequeueReusableCell(withIdentifier: "IncommingChatCell") as! IncommingChatCell
  let cellOutgoing = tableView.dequeueReusableCell(withIdentifier: "OutgoingChatCell") as! OutgoingChatCell

  let chatInfo = chatDataSourse[indexPath.row]
  if chatInfo.user == "receiver" {
    cellIncomming.chatLabel.text = chatInfo.chatString
    return cellIncomming
  }else {
    cellOutgoing.chatLabel.text = chatInfo.chatString
    return cellOutgoing
  }
}

if Condition1 {
    let cell : CellOne! = tableView.dequeueReusableCell( withIdentifier: "CellOne") as? CellOne
    return cell
}else if Condition2{
    let cell : CellTwo! = tableView.dequeueReusableCell( withIdentifier: "CellTwo") as? CellTwo
    return cell
}else{
    let cell : CellThree! = tableView.dequeueReusableCell( withIdentifier: "CellThree") as? CellThree
