Answer 1

let jsonData:NSDictionary = NSJSONSerialization.JSONObjectWithData(data!, options:NSJSONReadingOptions.MutableContainers , error: &error) as NSDictionary

if jsonData {
// process jsonData

var arrayofBOOKs: NSArray = jsonData["ListOfBooks"] as NSArray
for elem: AnyObject in arrayofBOOKs {
let name = elem["Book_name"] as String

println("Book_name: \(name)")
// here add the string to array 
 items.addObject(name)
}
tableView.reloadData

} else {
// couldn't load JSON, look at error
}

Here are the steps to follow:

Step-1

Open the ViewController.swift class and add a new tableview instance variable below the class declaration

@IBOutlet
var tableView: UITableView!

Step-2

To conform to the UITableViewDelegate and UITableViewDataSource protocol just add them seperated by colons afterUIViewController in the class declaration

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
override func viewDidLoad() {
    super.viewDidLoad()

    var  items = NSMutableArray()
    self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell")


}

step-3

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

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell

    cell.textLabel?.text =  items[indexPath.row]

    return cell
}

  func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    println("You selected cell #\(indexPath.row)!")
}
