title: retrieving core data into tableview cells swift
body: <p>I am trying to simply store and retrieve CoreData (something that I've done successfully before with swift). I was getting a nil for data, but now (not sure what changed) I'm not getting an error, just nothing showing in the tableview. I'm not sure if it's a problem in storing or retrieving the object. I've followed how I did it in another app of mine as closely as possible, but there seems to be some fundamental thing that I'm not getting. Here's what I have.</p>
  
  <p>My model:</p>
  
  <pre><code>import Foundation
  import CoreData
  
  @objc(DataModel)
  class DataModel: NSManagedObject {
  
  @NSManaged var itemName: String
  @NSManaged var quantity: NSNumber
  @NSManaged var price: NSNumber
  
  }
  </code></pre>
  
  <p>In my tableviewcontroller with static cells for text fields that I want to save data from:</p>
  
  <pre><code>import UIKit
  import CoreData
  
  class NewItemTableViewController: UITableViewController {
  
  @IBOutlet weak var itemNameTextField: UITextField!
  @IBOutlet weak var itemPriceTextField: UITextField!
  @IBOutlet weak var itemQuantityTextField: UITextField!
  
  
  override func viewDidLoad() {
      super.viewDidLoad()
  
  }
  
  override func didReceiveMemoryWarning() {
      super.didReceiveMemoryWarning()
      // Dispose of any resources that can be recreated.
  }
  
  
  @IBAction func saveButton(sender: AnyObject) {
      //CoreData
      let appDelegate = UIApplication.sharedApplication().delegate as AppDelegate
      let managedContext : NSManagedObjectContext = appDelegate.managedObjectContext!
      let entity =  NSEntityDescription.entityForName("Item", inManagedObjectContext: managedContext)
  
      var newItem = DataModel(entity: entity!, insertIntoManagedObjectContext: managedContext)
  
  
      newItem.itemName = itemNameTextField.text
      //newItem.price = itemPriceTextField.text
      //newItem.quantity = itemQuantityTextField
      managedContext.save(nil)
  
      self.navigationController?.popToRootViewControllerAnimated(true)
  
  
  }
  @IBAction func cancelButton(sender: AnyObject) {
      self.navigationController?.popToRootViewControllerAnimated(true)
  }
  </code></pre>
  
  <p>And in my tableviewcontroller that I want to retrieve the data an show in dynamic cells:</p>
  
  <pre><code>class ItemListTableViewController: UITableViewController {
  
  var items : Array&lt;AnyObject&gt; = []
  
  override func viewDidLoad() {
      super.viewDidLoad()
  }
  
  
  
  override func didReceiveMemoryWarning() {
      super.didReceiveMemoryWarning()
      // Dispose of any resources that can be recreated.
  }
  
  // MARK: - Table view data source
  
  override func numberOfSectionsInTableView(tableView: UITableView) -&gt; Int {
      // #warning Potentially incomplete method implementation.
      // Return the number of sections.
      return 1
  }
  
  override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
      // #warning Incomplete method implementation.
      // Return the number of rows in the section.
      return items.count
  }
  
  
  override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCell {
  
      let CellID: NSString = "cell"
      var cell: UITableViewCell = tableView.dequeueReusableCellWithIdentifier(CellID) as UITableViewCell
      var data: NSManagedObject = items[indexPath.row] as NSManagedObject
  
  
      var itemName = data.valueForKey("itemName") as String
      var price = data.valueForKey("price") as NSNumber
      var quantity = data.valueForKey("quantity") as NSNumber
  
  
      cell.textLabel!.text! = "\(itemName)"
      cell.detailTextLabel!.text! = "Price: \(price) - Quantity: \(quantity)"
  
      return cell
  
  }
  </code></pre>
  
  <p>Any help on a concept I might have missed somewhere in here would be appreciated! Thanks.</p>
  
  <p>Update: so I've redone my code to be modeled after @Bluehound 's suggestion. but I'm still getting an error: not sure how to fix it.
