Is possible to add some padding into an Array?

Question

I was wandering..... Is possible to add some padding into an array? For example: if i have something like var array:[NSDate] = [] What kind of data can i put inside the array as padding to obtain an array of 5 elements like array[NSDate, padding, NSDate, padding , padding].

I would like to maintain the position and the index of the elements also if some of them are nil.

Hope I made myself clear.

The answer is yes you can. And if you need more than 5 you can automate the process easily. (You can plug this into a playground to test it.)

func addPaddingTo( var myArray:[AnyObject], intArray:[Int]) -> [AnyObject]{

    //we'll do some checking here to make sure the indices you are changing are in fact valid members of myArray.

    for number in intArray {

        if number < myArray.count {

            myArray[number] = "Padding"
        }
    }

    return myArray
}


var paddedArray = Array < AnyObject >( count: 5, repeatedValue: NSDate())

paddedArray = addPaddingTo(paddedArray, intArray:[1,3,4])
