Swift - Core Data Attribute EXC Bad Access - ios

Question

I have a Swift app that I'm trying to use NSFetchedResultsController to populate four separate tableviews, which are in containers inside a main VC, using inheritance from a parent custom tableview controller class. I have a parent class with this method defined that all of my subclasses are inheriting:
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell
var task = fetchedResultsController.objectAtIndexPath(indexPath) as Task
if task.isKindOfClass(Task) == true {
cell.detailTextLabel?.text = task.name//EXC_BAD_ACCESS code=1
}
return cell
}
I commented the line where it is giving me the EXC_BAD_ACCESS compile error.
I know that the Task class object that inherits from NSManagedObject is successfully storing in that variable but it seems that whenever I try to access the name property (even println will cause the error), or any property on the object I get this compile error.
My hunch is that it has to do with four different tableviews trying to all access at once. I'm new to Core Data and not really sure.
EDIT
More code that might help with the problem:
let managedObjectContext = (UIApplication.sharedApplication().delegate as AppDelegate).managedObjectContext
var fetchedResultsController: NSFetchedResultsController = NSFetchedResultsController()
func getFetchedResultsController() -> NSFetchedResultsController {
fetchedResultsController = NSFetchedResultsController(fetchRequest: taskFetchRequest(), managedObjectContext: managedObjectContext!, sectionNameKeyPath: nil, cacheName: nil)
return fetchedResultsController
}
func taskFetchRequest() -> NSFetchRequest {
let fetchRequest = NSFetchRequest(entityName: "Task")
let sortDescriptor = NSSortDescriptor(key: "priority", ascending: true)
fetchRequest.sortDescriptors = [sortDescriptor]
return fetchRequest
}
override func viewDidLoad() {
super.viewDidLoad()
fetchedResultsController = getFetchedResultsController()
fetchedResultsController.delegate = self
fetchedResultsController.performFetch(nil)
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
}

Got it working! A few things: my name property was nil because I didn't set a default value in the model inspector and needed a default value for good measure, but more importantly: my managedObjectContext wasn't unwrapped with ! in its declaration and so I didn't unwrap it on every reference to it and so sometimes I was getting the optional(managedObjectContext?) when I needed the unwrapped value. It was let managedObjectContext = (UIApplication.sharedApplication().delegate as AppDelegate).managedObjectContext
but what it needed was let managedObjectContext = (UIApplication.sharedApplication().delegate as AppDelegate).managedObjectContext!. Optional problems and not being aware enough of when to unwrap were my downfall. I also deleted my initial app.sqlite because I ran into an issue there after I changed the model assigning the default value to name.
