Can't unwrap optional.None when accessing Label in Custom Table Cell - iOs Swift

Question

i am trying to display content in a custom cell in a table view. I started with a master detail application and tried to customize it. I created a new xib with the custom cell and connected it to a class and created the needed outlets.

This is the MasterView Controller (removed all functions I did not edit)

import UIKit

class MasterViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        var nipName=UINib(nibName: "SimpleTableCell", bundle:nil)
        self.tableView.registerNib(nipName, forCellReuseIdentifier: "cell")
        self.tableView.registerClass(SimpleTableCell.self, forCellReuseIdentifier: "cell")


        //Create Add Button
        let addButton = UIBarButtonItem(barButtonSystemItem: .Add, target: self, action: "insertNewObject:")
        self.navigationItem.rightBarButtonItem = addButton
        loadInitialData()
        tableView.reloadData()

    }

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        var  cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as SimpleTableCell
        cell.loadItem(user:"user1", hoop: "hoop1", post: "There is text in the table")
        return cell
    }
}

This is the Class for the custom cell

import UIKit

class SimpleTableCell : UITableViewCell{
    @IBOutlet var userLabel: UILabel
    @IBOutlet var hoopLabel: UILabel
    @IBOutlet var postLabel: UILabel


    func loadItem(#user: String, hoop: String, post: String) {
        userLabel = UILabel()
        hoopLabel = UILabel()
        postLabel = UILabel()
        userLabel.text = user
        hoopLabel.text = hoop
        postLabel.text = post 
    }

}

However I always get a "can't unwrap optional.none" in the loadItem function as soon as the text of userLabel is about to be changed - I don't get it because I initialise the labels right before I try to add text - or Am I wrong?

Thanks for any help.

no need to initialize your labels just before setting text. If you have nib then connect labels from nib to outlet — Johnykutty, Jul 15 '14 at 10:51

ok somehow installing the newest xcode beta and recreating the project solved the problem... Thanks for your help.

In your view did load you are registering class and nib of same cell for same cell identifier. If you have an xib drag and drop 3 labels in the cell and connect them to the IBOutlets, Also remove the line self.tableView.registerClass(SimpleTableCell.self, forCellReuseIdentifier: "cell"). If you are not using xib create labels, set frame and add them to the cell as subview in the method init(style: UITableViewCellStyle, reuseIdentifier: String!), also remove the line self.tableView.registerNib(nipName, forCellReuseIdentifier: "cell")

I am using xib - the IB Outlets are connected via drag & drop. When I remove self.tableView.registerClass(SimpleTableCell.self, forCellReuseIdentifier: "cell") the result is another error. SIGABRT on the call of var cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as SimpleTableCell – dschlossfr Jul 15 '14 at 16:40
have you changed the custom class of your cell in xib? – Johnykutty Jul 16 '14 at 04:42
yes the cell is assigned to the custom class "SimpleTableCell" - which is shown in my first post. – dschlossfr Jul 16 '14 at 12:03
