Welcome to the Treehouse Community
Looking to learn something new?
whats wrong with my code?
var arrayOfInts = [1,2,3,4,5,6] arrayOfInts.append(7) arrayOfInts +  let value = arrayOfInts arrayOfInts.append(8) arrayOfInts +  let value = arrayOfInts

It looks like you've added the new Int of 7 without actually assigning it back to the array.
arrayOfInts +  doesn't actually assign your concatenation back to the array arrayOfInts. To achieve this you could do either of the following:
arrayOfInts = arrayOfInts +  OR arrayOfInts += 
Hope that helps!
