Overriding method with selector has incompatible type - Swift

Overriding UITableViewDelegate's tableView:cellForRowAtIndexPath: is causing the following compile error:

Overriding method with selector 'tableView:cellForRowAtIndexPath:' has incompatible type '(UITableView!, NSIndexPath!) -> UITableViewCell!'

The current implementation of the override function is:

override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!
{
    let cell = tableView.dequeueReusableCellWithIdentifier("cellIdent", forIndexPath: indexPath) as UITableViewCell

    // Configure the cell...

    return cell
}

What is causing the error and how can it be fixed?

Try this:

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

This may help: Overriding method with selector '***' has incompatible type '****' parse

Remove implicit optional type.Check in UITableViewDataSource there is no optional for tableView,indexPath.Also remove override as you implementing the protocol methods you do not need to write override

Replace with below method

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
    //the error is on the line oboe... Overriding method with selector 'tableView:cellforRowAtIndexPath:'has incompatible type '(TableView, NSIndexpath) -. UITableViewCell!'
{
    let cell = tableView.dequeueReusableCellWithIdentifier("cellIdent", forIndexPath: indexPath) as UITableViewCell

    // Configure the cell...

    return cell
}
