Swift prepareForSegue initializes empty array - swift

Question

when I pass data from FirstViewController to SecondViewController (table view) via prepareForSegue I have an empty array in secondViewController to collect the data, but every time the view loads the array is init as empty.
Before getting into core data or nsuserdefaults, how can I add the data tho the second view controller?
There is a similar problem here but the method has not solved my problem.
Trouble passing Array through prepareForSegue
// View Controller
// a new dictionary object is created
myDictionary = ["apples": 3, "oranges": 4, "bananas": 5]
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "saveData" {
let dvc = segue.destionationViewController as! MyTableViewController
dvc.arrayOfDictionaries += [myDictionary]
}
resetAll()
}
// My Table View Controller
var arrayOfDictionaries: [[String: AnyObject]] = []
var dictionary = [String:AnyObject]()
in TableViewContrller I have a func
override func viewDidLoad() {
super.viewDidLoad()
loadData() //
}
func loadData() {
for dict in arrayOfDictionaries {
for (key, value) in dict {
// extract data
dictionary[key] = value
}
}
}
How can I get data to persist in arrayOfDictionaries?
Thanks

Why are you appending values to the array if it is empty?
To avoid future problems, you can just call
dvc.arrayOfDictionaries = [myDictionary]
So you'll never care about the arrayOfDictionaries state (if it is initialized, if it's empty or anything else)
And please, check your viewDidLoad and other view-lifecycle methods in the table view controller. Is possible that you're initializing again the array there?
