I am trying to print a revered array so the latest entry will be the first one to show up. But the problem I am having is that arrays are not being printed in the way I would like. If i print 3 numbers from 3-1 it shows up 1,3, 2 not 3,2,1. I realize that this is mostly a logic problem but I do not know where to start. I have added the main parts of the array.

   var arrayOfInt = [Int]()

 @IBAction func addNumber(_ sender: Any) {
 arrayOfInt.append(number)
            print(arrayOfInt)
            arrayOfInt = arrayOfInt.reversed()
            let formatter = DateFormatter()formatter.dateFormat = "dd.MM.yyyy HH:mm"
            label.text = arrayOfInt.map { "Date | \(Date.formattedNow) | \($0)" }.joined(separator:"\n")
}

Just insert the elements at index 0 (http://stackoverflow.com/q/24002733/2976878) – Hamish May 07 '17 at 20:53
Could you show me how to do that. – May 07 '17 at 21:14
I tried that but it just added another entry for every entry entered. – May 07 '17 at 22:49
Just replace the call to `append` with `arrayOfInt.insert(number, at: 0)`, then get rid of the call to `reversed()`. – Hamish May 07 '17 at 22:52
That is it Thank You – May 07 '17 at 23:09
