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.
