UITableView Custom Cell not working

My program keeps crashing in the cellForRowAtIndexPath method when I am trying to create a custom table cell. I have put a breakpoint on each line in the code, and the code fails after I try creating the cell variable with the error: unexpectedly found nil while unwrapping optional value. I have used custom table cells successfully many times before and have not run into this issue. It seems simple but I can't figure out what is wrong. Perhaps something in xcode changed that I'm unaware of? Any help is appreciated. Thanks!... Also, I did in fact register my custom cell in viewDidLoad. I'll include that code as well. 

var nib = UINib(nibName: "FeedTableViewCell", bundle: nil)
tableView.registerNib(nib, forCellReuseIdentifier: "feedCell")

Probem Code Below:

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    var cell:FeedTableViewCell = tableView.dequeueReusableCellWithIdentifier("feedCell", forIndexPath: indexPath) as! FeedTableViewCell

    cell.descriptionLabel.text = "Testing the description label of my cell."

    return cell
}

Update

The one difference between this project and others that have worked is that Xcode is now prompting me to put a bang (!) after as, whereas before I never used one. If I don't add (!) it gives me the error message "AnyObject is not convertible to FeedTableViewCell"

as! FeedTableViewCell -instead of- as FeedTableViewCell

FeedTableViewCell Class

import UIKit

class FeedTableViewCell: UITableViewCell {

    @IBOutlet weak var descriptionLabel: UILabel!
    @IBOutlet weak var priceLabel: UILabel!

    override func awakeFromNib() {
        super.awakeFromNib()
        priceLabel.font = UIFont(name: "AvenirNext-Bold", size: 30.0)
    }

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)
    }
}

After spending way too much time trying to get it to work. I nuked my custom table cell, created a brand new one, set it up the exact same way, and everything is working fine now. Still have no idea what happened, but I guess the lesson from this is that sometimes you just have to nuke it and start over.

you should used like this

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

    let cell = tableView.dequeueReusableCellWithIdentifier("feedCell", forIndexPath: indexPath) as FeedTableViewCell


    cell.descriptionLabel.text = "Testing the description label of my cell."

    return cell
}

You should use 

var cell:FeedTableViewCell = tableView.dequeueReusableCellWithIdentifier("feedCell",) as! FeedTableViewCell

NSIndexPath may make this issue.

HTH, Enjoy Coding !!
