Data is only displayed when clicked on in tableview

I am working on an app with a table view. The table view displays a lot of data and in a few rows the detailTextlabel is only displayed when I click on it.

This is the extension I am using to create the table view:

extension TicketViewController: UITableViewDelegate, UITableViewDataSource {

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    switch section {
    case 0:
        return TicketsDataSource.sharedInstance.storesPR.count
    case 1:
        return TicketsDataSource.sharedInstance.storesRJ.count
    case 2:
        return TicketsDataSource.sharedInstance.storesSC.count
    case 3:
        return TicketsDataSource.sharedInstance.storesSP.count
    default:
        return 0
    }
}

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 4
}

func tableView(tableView: UITableView, estimatedHeightForHeaderInSection section: Int) -> CGFloat {
    return 30
}

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return 30
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath)

    switch indexPath.section {
    case 0:
        cell.textLabel?.text = TicketsDataSource.sharedInstance.storesPR[indexPath.row]
        cell.detailTextLabel?.text = TicketsDataSource.sharedInstance.addressPR[indexPath.row]
    case 1:
        cell.textLabel?.text = TicketsDataSource.sharedInstance.storesRJ[indexPath.row]
        cell.detailTextLabel?.text = TicketsDataSource.sharedInstance.addressRJ[indexPath.row]
    case 2:
        cell.textLabel?.text = TicketsDataSource.sharedInstance.storesSC[indexPath.row]
        cell.detailTextLabel?.text = TicketsDataSource.sharedInstance.addressesSC[indexPath.row]
    case 3:
        cell.textLabel?.text = TicketsDataSource.sharedInstance.storesSP[indexPath.row]
        cell.detailTextLabel?.text = TicketsDataSource.sharedInstance.addressesSP[indexPath.row]
    default:
        cell.textLabel?.text = ""
        cell.detailTextLabel?.text = ""
    }

    cell.textLabel?.textColor = UIColor.whiteColor()
    cell.textLabel?.font = UIFont.systemFontOfSize(12)

    // While loops to fulfill the tableview
    // Cities of Paraná
    var i = 0
    while i < dataSingleton.citiesPR.count {
        setCell(cell, text: dataSingleton.citiesPR[i])
        i += 1
    }

    // Cities of Rio de Janeiro
    i = 0
    while i < dataSingleton.citiesRJ.count {
        setCell(cell, text: dataSingleton.citiesRJ[i])
        i += 1
    }

    // Fixing bug where SÃO JOÃO DE MERITI was not being displayd differently
    if cell.textLabel?.text == "SÃO JOÃO DE MERITI" {
        cell.textLabel?.font = UIFont.systemFontOfSize(16)
        cell.textLabel?.textColor = UIColor.blackColor()
    }

    // Cities of Santa Catarina
    i = 0
    while i < dataSingleton.citiesSC.count {
        setCell(cell, text: dataSingleton.citiesSC[i])
        i += 1
    }

    // Cities of São Paulo
    i = 0
    while i < dataSingleton.citiesSP.count {
        setCell(cell, text: dataSingleton.citiesSP[i])
        i += 1
    }

    return cell
}

private func setCell(cell: UITableViewCell, text: String) {
    if cell.textLabel?.text == text {
        cell.textLabel?.font = UIFont.systemFontOfSize(16)
        cell.textLabel?.textColor = UIColor.blackColor()
    }
}

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    tableView.deselectRowAtIndexPath(indexPath, animated: false)
}

func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    var label = ""
    switch section {
    case 0:
        label = TicketsDataSource.sharedInstance.states[0]
    case 1:
        label = TicketsDataSource.sharedInstance.states[1]
    case 2:
        label = TicketsDataSource.sharedInstance.states[2]
    case 3:
        label = TicketsDataSource.sharedInstance.states[3]
    default:
        label = ""
    }

    return label
}

func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
    if let header = view as? UITableViewHeaderFooterView {
        header.textLabel!.font = UIFont.systemFontOfSize(18)
        header.textLabel!.textColor = UIColor.whiteColor()
    }
}

}

As you guys can see, the <code>detailTextLabel</code>, for the middle of the table view on, only displays the data when I click on it

I am not sure if the problem relies on cellForRowAtIndexPath or somewhere else.

The TickersDataSource is mainly a file with arrays.

Any thoughts?

Thanks in advance!

Is it possible your textColor for the detailTextlabel is the same color as the background initially and then changes to black when you click/highlight the cell?
