Swift crashes after TableViewCell pressed - ios

Question

My app keeps crashing when I select the TableViewCell but it does not give me an error message. Hope some on can help. Below is the TableView Controller and the View Controller code. I have added the date into the cordite model and think it has something to do with that.
import UIKit
import CoreData
class DiveLogTableViewController: UITableViewController {
var myDivelog : Array<AnyObject> = []
override func viewDidLoad() {
super.viewDidLoad()
// 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()
}
override func viewDidAppear(animated: Bool) {
let appDel:AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
let context:NSManagedObjectContext = appDel.managedObjectContext!
let freq = NSFetchRequest(entityName: "Divelog")
myDivelog = context.executeFetchRequest(freq, error: nil)!
tableView.reloadData()
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "update" {
var selectedItem: NSManagedObject = myDivelog[self.tableView.indexPathForSelectedRow()!.row] as! NSManagedObject
let ADLVC: AddDiveLogViewController = segue.destinationViewController as! AddDiveLogViewController
ADLVC.divenumber = selectedItem.valueForKey("divenumber") as! String
ADLVC.ddate = selectedItem.valueForKey("ddate") as! NSDate
ADLVC.divelocation = selectedItem.valueForKey("divelocation") as! String
ADLVC.existingItem = selectedItem
}
}
