Answer 1

My code:

override func viewDidLoad() {
    super.viewDidLoad()
     tableView.register(
         UINib(nibName: "XibCell", bundle: nil), 
         forCellReuseIdentifier: "Cell"
     )
 }

func tableView(_ tableView: UITableView, 
               cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") 
    return cell as! UITableViewCell
}

Answer 2

In viewDidLoad register XIB as shown below

var userDetailsNIB = UINib(nibName: "UserDetailsCell", bundle: nil)
        viewListingTable.registerNib(userDetailsNIB, forCellReuseIdentifier: "UserDetailsViewCellID")

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

function use it by access it with Identifier which created in viewDidLoad method

let cell = tableView.dequeueReusableCellWithIdentifier("UserDetailsViewCellID") as UserDetailsViewCell

return cell

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
   // Do additional code here
}

Don’t 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.
}

1. Register your NIB with the reuse identifier:

   override func viewDidLoad() {
       super.viewDidLoad()
       tableView.registerNib(UINib(nibName: "devicedet", bundle: nil), forCellReuseIdentifier: "Cell")
   }
   

2. Your cellForRowAtIndexPath would then instantiate the cell.

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

import UIKit
    class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    //MARK:- Sample Data Array to load in TableView
        let sampleArrray: \[String\] = \["val1", "val2", "val3", "val4", "val5"]

    //MARK:- Cell reuse identifier 
        let cellReuseIdentifier = "cell"


    //MARK:- UITableView outlet 
         @IBOutlet var tableView: UITableView!

          override func viewDidLoad() {
            super.viewDidLoad()

            // Registering the custom cell

            self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier)

            // Setting delegate and Datasourse as same viewcontroller (this code is not neccessory if we are setting it from storyboard)

            tableView.delegate = self
            tableView.dataSource = self
        }
    //UITableview required methods 

        func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            return sampleArrray.count
        }

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

            cell.textLabel?.text = sampleArrray\[indexPath.row\]

            return cell
        }

        func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
           print("clicked at: \(indexPath.row)")
           //Here u can get the selected cell and add action related to this cell seelction 
        }

Added Screenshot for setting Datasource and delegate from storyboard

Your fuction registerNib , you try to write in viewDidLoad() method and remove from cellForRowAtIndexPah and then test your project

Your Cell Instance should be of CustomCell instance and not of UITableView Cell. var cell :UITableViewCell should be replaced by var cell :devicedet
