iOS Swift 2.0 Collections and Control Flow Introduction to Collections Working with Arrays

Swift

Challenge Task 2 of 4

Now that we have an array declared, since it is a mutable array, we can add and remove items. Let's start by adding two more values to our existing array. There are two ways we can add items to an array and I want you to give both a try. 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.

Add another item to the array by concatenating an array. When concatenating, assign the results of the expression back to arrayOfInts.

no work

arrays.swift 
// Enter your code below

var arrayOfInts = [1,2,3,4,5,6,7]
var arrayOfInts.append  [8]

Hey Ary,

To append an element onto the array, you need to use the append function. Like this:

arrayOfInts.append(8)

Good luck! :)
