Search Bar on TableView Does not Work

Question

I'm trying to add a search bar to a simple table view consisting of 7 cells of names and small description for each name.

As in the image here:

I made a class in swift file called Business, that has two attributes: Name and Des.

Here's the code in the view controller:

  class FirstViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
@IBOutlet weak var TableView: UITableView!
var B = [Business]() //candies
var filteredNames = [Business]()

 let searchController = UISearchController(searchResultsController: nil)

func filterContentForSearchText(searchText: String, scope: String = "All") {
    filteredNames = B.filter { Bu in
        return Bu.Name.lowercaseString.containsString(searchText.lowercaseString)
    }

    TableView.reloadData()
}


override func viewDidLoad() {
    super.viewDidLoad()


    B = [
        Business(Name:"Mariah", Des:"I'm Here to help"),
        Business(Name:"Nada", Des:"Hi"),
        Business(Name:"Atheer", Des:"Hello"),
        Business(Name:"Lojian", Des:"I can Help you"),
        Business(Name:"Nadya", Des:"Hayat"),
        Business(Name:"Omnia", Des:"Yahoo"),
        Business(Name:"Eman", Des:"I have amazing stuff"),
        Business(Name:"Amani", Des:"Yess")
    ]

    searchController.searchResultsUpdater = self
    searchController.dimsBackgroundDuringPresentation = false
    definesPresentationContext = true
    TableView.tableHeaderView = searchController.searchBar

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

 func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if searchController.active && searchController.searchBar.text != "" {
        return filteredNames.count
    }
    return B.count
}

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

    let cell = self.TableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! CellTableViewCell

    cell.NameLabel.text = B[indexPath.row].Name
    cell.DescriptionLabel.text = B[indexPath.row].Des

    let Bu: Business

    if searchController.active && searchController.searchBar.text != "" {
        Bu = filteredNames[indexPath.row]
    } else {
        Bu = B[indexPath.row]
    }
     cell.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator
     return cell
}


  }

 extension FirstViewController: UISearchResultsUpdating {
func updateSearchResultsForSearchController(searchController:   
(UISearchController)   {
filterContentForSearchText(searchController.searchBar.text!)
}
 }

I followed this tutorial to do that: https://www.raywenderlich.com/113772/uisearchcontroller-tutorial

I don't know whay when I tried to search in simulator the result is always the first cell: Mariah

What's wrong with the code?

in your code you have set the both the label from the B before you check the condition if it's from filter result or normal, dasdom answer should mostly work for you — HardikDG

You don't use the search result to populate the cells. Replace you cellForRowAtIndexPath with this:

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

    let cell = self.TableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! CellTableViewCell

    let Bu: Business

    if searchController.active && searchController.searchBar.text != "" {
        Bu = filteredNames[indexPath.row]
    } else {
        Bu = B[indexPath.row]
    }

    cell.NameLabel.text = Bu.Name
    cell.DescriptionLabel.text = Bu.Des

    cell.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator
    return cell
}

And, don't use capital first letters for properties.
