Answer 1

Add UITableView To UIView.Add custom cells, associate custom cell classes and implement delegates -UITableviewDelegate and UITableViewDataSource .

case 1: Two custom cells on tableview

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

  var cell: CustomCell!

  if indexPath.row == 0{
    cell = tableView.dequeueReusableCellWithIdentifier("Cell1ID", forIndexPath: indexPath) as CustomCell
    //set cell2
  }
  if indexPath.row >= 1{
    cell = tableView.dequeueReusableCellWithIdentifier("Cell2ID", forIndexPath: indexPath) as CustomCell
    let cons = aArray[indexPath.row - 1]
    // set cell2 
  }
  return cell
}

case 2: alternate display of custom cells (i.e. using uisegmentcontrol)

var CellIdentifier: String = "Cell1ID"

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
       if (CellIdentifier == "Cell1ID")
    {
let cell = tableView.dequeueReusableCellWithIdentifier(CellIdentifier)! as! FirstTableViewCell

//additional code
return cell

}
else {
let cell = tableView.dequeueReusableCellWithIdentifier(CellIdentifier)! as! SecondTableViewReportsCell

//Additional code

return cell
}
}

case 3: Alternate custom cells (i.e., odd even)

var CellIdentifier: String = "Cell1ID"

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

var cell: CustomCell!

if (indexPath.row % 2 == 0) {

let cell = tableView.dequeueReusableCellWithIdentifier(CellIdentifier)! as! FirstTableViewCell
   
}
else
{
        let cell = tableView.dequeueReusableCellWithIdentifier(CellIdentifier)! as! SecondTableViewCell
}
return cell
}
