My code looks fine but I don't know what could be wrong with my concatenating and appending method

Please help with the last two lines of code and view my comment

array.swift
// Enter your code below
var arrayOfInts = [1,2,3,4,5,6]
arrayOfInts.append(7)
arrayOfInts +=[8]//Tried using this aswell arrayOfInts + [8]

Hi there! You're doing great! The reason this one isn't passing is because you're missing a space. Seriously, just a space. There should be a space between your += and your [8].

Also, you stated you tried arrayOfInts + [8], but you never said if you assigned it back into arrayOfInts. That would also work and should look like this:

arrayOfInts = arrayOfInts + [8]

Hope this is helpful! :sparkles:
