Retrieving data from Parse.com (Swift) - swift

Question

I am attempting to fetch data from an object created on Parse.com into a custom cell that contains labels and images. The code I implemented thus far runs but my tableview remains empty and at runtime displays the following error. ERROR: Thread 1: Exc_BAD_INSTRUCTION (Code =EXC_1386_INVOP, subcode=0x0). Can someone please explain why this is occurring I am new to programming in Xcode.
#objc
protocol ViewControllerDelegate {
optional func toggleLeftPanel()
optional func toggleRightPanel()
optional func collapseSidePanels()
}
class ViewController: UITableViewController, UITableViewDataSource, UITableViewDelegate
{
var delegate: ViewControllerDelegate?
var arrayOfParties: [Information] = [Information]()
#IBAction func menuTapped(sender: AnyObject) {
delegate?.toggleLeftPanel?()
}
override func viewDidLoad()
{
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.loadData()
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
//return self.arrayOfParties.count
return self.arrayOfParties.count
}
//Function to adjust the height of the custom cell
override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat
{
return 230
}
override func tableView(tableView: UITableView,cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cell: CustomCell = tableView.dequeueReusableCellWithIdentifier("Cell") as! CustomCell
let party = arrayOfParties[indexPath.row]
cell.setCell(party.partyName, promoterLabelText: party.promoterName, partyCostLabelText: party.partyCost, partyFlyerUIImage: party.flyerImage, promoterUIImage: party.promoterImage)
return cell
}
func loadData()
{
var findDataParse:PFQuery = PFQuery(className: "flyerDataFetch")
findDataParse.findObjectsInBackgroundWithBlock{
(objects: [AnyObject]?, error: NSError?)->Void in
if (error == nil){
for object in objects!
{
var party1 = Information(partyName: (object["partyName"] as? String)!, promoterName: (object["promoterName"] as? String)!, partyCost: (object["partyCost"] as? String)!, flyerImage: "", promoterImage: "")
self.arrayOfParties.append(party1)
}
}
else {
// something went wron
}
}
}
}

The problem is that you probably have cells in the tableview already that don't have the new labels/images.
You need to tell the program to insert a type of text where there is no input of the new type.
In this case I have already since a month back worked on a project, and now I started inserting more labels into my cell, thats where the problem pops up, so the previous cells don't have this information.
So I just tell the system to check all cells, if a cell doesn't have the needed text, it should just enter some placeholder text (in this case = "").
if let content = text.objectForKey("Content") as? String {
cell.TextView.alpha = 1.0
cell.TextView.text = content
}
else{
cell.TextView.alpha = 1.0
cell.TextView.text = ""
}
I hope this helps, I have only explained how to do, I haven't really told you were in your code to do it, but from what I see you should input the code right under the part where you declare "Party1".
