How to get custom data from Parse without issues

Question

If you look here https://i.sstatic.net/bJGW2.jpg you can see my issue.

if PFUser.currentUser()!.objectForKey("receivedItems") != nil && PFUser.currentUser()!.objectForKey("sentItems") != nil {

        PFUser.currentUser()!.addObject(receivedItemsArr, forKey: "receivedItems")
        PFUser.currentUser()!.addObject(sentItemsArr, forKey: "sentItems")

    } else {

        var qry = PFQuery()

        receivedItemsArr = PFUser.currentUser()!.objectForKey("receivedItems") as! [GroceryItem]
        sentItemsArr = PFUser.currentUser()!.objectForKey("sentItems") as! [GroceryItem]

    }

I want to make a custom array object if it doesn't exist yet, but when I try to access it in the else statement , it gives me this error

Warning: A long-running operation is being executed on the main thread. 
 Break on warnBlockingOperationOnMainThread() to debug.
fatal error: unexpectedly found nil while unwrapping an Optional value

and crashes the app . Do I have to use a PFQuery? I don't know how to! could you help with code that would help with the error in the else statement and possibly fix it?

Answer 1

for this specific question, it was a logic problem. i had to swithc it from != to == for it to make sense
