UITableView in Swift

Question

I\'m struggling to figure out what\'s wrong with this code snippet. This is currently working in Objective-C, but in Swift this just crashes on the first line of the method.

UITableView Demo using Playground

//: Playground - noun: a place where people can play

import UIKit
import PlaygroundSupport

class TableviewDemoDelegate:NSObject,UITableViewDataSource,UITableViewDelegate {


    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 100
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        var cell:UITableViewCell? = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath as IndexPath)

        if cell == nil {
            cell = UITableViewCell(style: .default, reuseIdentifier: "cell")
        }


        cell?.textLabel?.text = "Item \(indexPath.row+1)"

        return cell!
    }


    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        print("You have selected cell #\(indexPath.row)!")

    }
}

var tableView = UITableView(frame:CGRect(x: 0, y: 0, width: 320, height: 568), style: .plain)
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")

let delegate = TableviewDemoDelegate()
tableView.delegate = delegate
tableView.dataSource = delegate


PlaygroundPage.current.liveView = tableView
