Getting custom array contents back from Parse and sending them back to Parse

Question

If you look here:

You will see that I made a PFUser and added two new objects to it, a sentItems array and a receivedItems array. In my code I wanted to access those and append and change them, so I asked for help and got this:

var receivedItemsArr = PFUser.currentUser()!["receivedItems"] as? [Item]
var sentItemsArr = PFUser.currentUser()!["sentItems"] as? [Item]

Item is just an object that I made that I want the array to hold. This doesn't work; it won't save, nor will it get for me what's in the array.

What Swift code do I need to write that would help me in the fact that it would make two new variables that would be the contents of those arrays from Parse, and that I would be able to save them back?

Answer 1

Lets say you have create a new class named "Data".

var dummy = ["1","2"]
var dummy2 = ["3","4"]
var ObjectsToSave = PFObject(className: "Data")
var username = PFUser.currentUser()?.username
ObjectsToSave["receivedItems"] = dummy
ObjectsToSave["sentItems"] = dummy2
ObjectsToSave["username"] = username
    ObjectsToSave.saveEventually { (success:Bool, error:NSError?) -> Void in
        if error == nil {
        // there is no error so object was save
        }
        else{
        // error
        }
    }

I think you are looking for something like that
