How do I concatenate two arrays?

It says that i need to concatenate and use the + operator. Have I forgotten how to do this? Help is great. Thanks.

array.swift 
// Enter your code below

var arrayOfInts = [1,2,3,4,5,6]

arrayOfInts.append (7)

var anotherItem = [8,9]

var arrayofInts = arrayOfInt + anotherItem
