hello friends,
if you would like to Load custom cell(Xib) in UITableView in swift ,you may use the following code ->

 func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return array.count;   //This function returns number of rows in table view
    }


 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        var cell:YourTableViewCell! = tableView.dequeueReusableCellWithIdentifier("YourTableViewCell", forIndexPath:indexPath)as! YourTableViewCell
        // This function actually loads the xib
        if cell == nil{
            let cellnib = [NSBundle.mainBundle().loadNibNamed("YourTableViewCell", owner:self, options: nil)]
            cell = cellnib.first! as! YourTableViewCell

        }
     // Do additional code here
    }

Dont forget to register nib in viewDidLoad

override func viewDidLoad() {

        super.viewDidLoad()
       // registering your nib
        let yourNibName = UINib(nibName: "YourTableViewCell", bundle: nil)
        tableView.registerNib(yourNibName, forCellReuseIdentifier: "YourTableViewCell")

        // Do any additional setup after loading the view.
    }
