Since the array is mutable, let's add two more values to the existing array. There are two ways we can add items to an array and I want you to give both a try. First, add one item to the array using the append method.
Remember: We invoke methods on an array using a period or dot. After the dot we write out the method name and a value to append in parentheses following the name.
Next, add another item to the array by concatenating an array. When concatenating, assign the results of the expression back to arrayOfInts.
var arrayOfInts = (1,2,3,4,5,6)
arrayOfInts.append(7)
arrayOfInts.append(8)
arrayOfInts + (7) + (8)

4,711 PointsThe wording of the question is really confusing. It turns out it just wants you to add one int for the append and one int for the concatenation
var arrayOfInts = [1,2,3,4,5,6]
arrayOfInts.append(7)
arrayOfInts += [8]

this works. Xcode places the values of () in the code when you blow the auto function to work. var arrayOfInts = [1, 2, 3, 4, 5, 6] arrayOfInts.append(7) arrayOfInts += [8]

you should rewatch the video. In Swift you declare an array with [] and not (). Also concatinating an array means arrayOfInts += [7, 8].

It turns out that they only want one value per added array.
Like such:
arrayOfInts.append(x)
arrayOfInts += [x]
