ios swift uitableview add last cell

I want to add a cell into my tableview to the last row using another UserInterface.The code is like this.

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    var cell:JoinCell = tableView.dequeueReusableCellWithIdentifier(reuseIdentifier, forIndexPath: indexPath) as! JoinCell

    let lastSectionIndex = tableView.numberOfSections-1
    let lastSectionLastRow = tableView.numberOfRowsInSection(lastSectionIndex) - 1
    let lastIndexPath = NSIndexPath(forRow:lastSectionLastRow, inSection: lastSectionIndex)

    let cellIndexPath = tableView.indexPathForCell(cell)

    if cellIndexPath == lastIndexPath {
        cell = tableView.dequeueReusableCellWithIdentifier("JoinFooterCell") as! JoinFooterCell
    }

I got error message "Cannot assign value of type 'JoinFooterCell' to type 'JoinCell'"

Does anyone can give me advise? Thanks.

Let try this:

var cell: UITableViewCell!
if cellIndexPath == lastIndexPath {
    cell = tableView.dequeueReusableCellWithIdentifier("JoinFooterCell") as! JoinFooterCell
} else {
    cell = tableView.dequeueReusableCellWithIdentifier(reuseIdentifier, forIndexPath: indexPath) as! JoinCell
}
return cell

Do this and for datasource.sections.count use the same value you return in numberOfSectionInTableView() and for datasource.rows.count use the same value you return in your numberOfRowsForSection()

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    if datasource.sections.count - 1 == indexPath.section && datasource.rows.count - 1 == indexPath.row {
        let cell = tableView.dequeueReusableCellWithIdentifier("JoinFooterCell") as! JoinFooterCell
        return cell
    } else {
        let cell = tableView.dequeueReusableCellWithIdentifier(reuseIdentifier, forIndexPath: indexPath) as! JoinCell
        return cell
    }
}

Do something like this 

let lastSectionIndex = tableView.numberOfSections-1
let lastSectionLastRow = tableView.numberOfRowsInSection(lastSectionIndex) - 1
let lastIndexPath = NSIndexPath(forRow:lastSectionLastRow, inSection: lastSectionIndex)

let cellIndexPath = tableView.indexPathForCell(cell)
var cell
if cellIndexPath == lastIndexPath {
    cell = tableView.dequeueReusableCellWithIdentifier("JoinFooterCell") as! JoinFooterCell
}
else {
    cell = tableView.dequeueReusableCellWithIdentifier(reuseIdentifier, forIndexPath: indexPath) as! JoinCell
}

What actually am trying to do is create cell which you want to return. Don't initialize the cell first and then try to re assign. First determine whether its the last cell and based on that, initialize the kind of cell you want.
