Estou trabalhando em uma exibição de tabela com uma célula personalizada que foi criada programaticamente, sem uso do IB. Procurei no Google e perguntei no NSChat, mas ainda não consigo fazê-lo funcionar. Apenas exibe a exibição de tabela padrão. Desde já, obrigado!

EventCell.swift

import UIKit

class EventCell: UITableViewCell {

    var eventName: UILabel = UILabel()
    var eventCity: UILabel = UILabel()
    var eventTime: UILabel = UILabel()

    override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)

        self.contentView.addSubview(eventName)
        self.contentView.addSubview(eventCity)
        self.contentView.addSubview(eventTime)
    }

    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override func layoutSubviews() {
        super.layoutSubviews()

        eventName = UILabel(frame: CGRectMake(20, 10, self.bounds.size.width - 40, 25))
        eventCity = UILabel(frame: CGRectMake(0, 0, 0, 0))
        eventTime = UILabel(frame: CGRectMake(0, 0, 0, 0))

    }

}

ViewController.swift

class ViewController: UITableViewController, UITableViewDelegate {

    var events: Dictionary<String, [String]> = ["0": ["Monroe Family", "La Cañada", "8:30"]]

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.dataSource = self;
        tableView.delegate = self;

        tableView.registerClass(EventCell.self, forCellReuseIdentifier: "EventCell")
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()

    }

    override func tableView(tableView: UITableView, estimatedHeightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
        return UITableViewAutomaticDimension;
    }

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

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

        var cellIdendifier: String = "EventCell"

        var cell: EventCell = tableView.dequeueReusableCellWithIdentifier(cellIdendifier, forIndexPath: indexPath) as EventCell
        cell = EventCell(style: .Default, reuseIdentifier: cellIdendifier)

        if let i = events[String(indexPath.row)] {
            cell.eventName.text = i[0]
            cell.eventCity.text = i[1]
            cell.eventTime.text = i[2]
        }

        cell.sizeToFit()

        return cell


    }
}
