What does it mean i have to use the + operator?

I asked this once and I tried what the guy said, but it still doesnt work. Thanks for helping.

array.swift 
// Enter your code below

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

arrayOfInts.append (7)


var arrayofInts = arrayofInts + [8]

You've got the logic spot on, so don't beat yourself up too much! The problem here is that you're creating a new variable named 'arrayofInts', whereas the task wants you to continue using the variable 'arrayOfInts'.

By concatinating the arrays and assigning it to your existing variable, you should satisfy the requirements of this task.

arrayOfInts = arrayOfInts + [8]

I hope this helps!
