There are two ways to add an item to array the task is asking for you to add item using both ways below

  1. You can add a new item to the end of an array by calling the array’s append(_:) method:
  2. You can append an array of one or more compatible items with the addition assignment operator (+=):
var arrayOfInts: [Int] = [1,2,3,4,5,6]

arrayOfInts.append(7)
arrayOfInts += [8]
