Iterate through Struct to upload to Firebase

I have this struct:

struct CartItem {

    var name: String = ""

    var count = Int()

}



 var itemsInCart : [CartItem] =

I append to it with a button:

 @IBAction func addButton(_ sender: UIButton){



        if let index = itemsInCart.index(where: { $0.name == name })   {

            itemsInCart[index].count += 1



        } else {

            itemsInCart.append(CartItem(name: name, count: 1))

        }    

}

Now, I want to upload this to firebase. When I do this:

@IBAction func orderButton(_ sender: UIButton) {



        for items in itemsInCart {



        //Write to firebase

        var dataArray = "(items.count) (items.name)"

        let data = ["CreatedOn" : timeStamp, "Order" : dataArray] as [String : Any]

        self.ref?.child(dateAndTime).updateChildValues(data, withCompletionBlock: { (error, ref) in

            if error != nil{

                print(error!)

                return

            }



        })

        let userData = ["CreatedOn" : timeStamp, "Order" : data] as [String : Any]



            break

        }

    }

The problem with this is that its only writing the last appended value to Firebase. How can I get it to include the whole Struct?

If the user orders first: 2 bananas and then: 3 apples, firebase should read:

2 bananas

3 apples

Now it just reads 3 apples.
