When i look up how to concatenate, I see to use the following =+. This is telling me to use + only. Which one is correct

I've tried several times to concatenate without luck. I'm not sure what I am missing.

arrays.swift 
// Enter your code below
var arrayOfInts = [(1), (2), (3), (4), (5), (6)]

arrayOfInts.append(7)

arrayOfInts += (8)

Hi,

You are asked to assign it to arrayOfInts, which means you have to write something starting with "arrayOfInts = ..."

Here I'd try : arrayOfInts = arrayOfInts + [8]

I use square brackets as I need two arrays to be able to use concatenation.

Hope this helps!

Julien
