Bug in Challenge Task 2 of 4: Keep getting the error "Oops, looks like Task 1 is no longer passing."

I started with the following code: var arrayOfInts:[Int] = [4, 5, 6, 34, 2, 1] This passed task 1. Then I added the following: arrayOfInts.append(444) arrayOfInts += [7, 8]

Now I keep getting the error "Oops, looks like Task 1 is no longer passing.". I have verified the code in Playground and it works fine, not sure why this error occurs. Is this a bug in the challenge?

array.swift 
var arrayOfInts:[Int] = [4, 5, 6, 34, 2, 1]
arrayOfInts.append(444)
arrayOfInts += [7, 8]

The error message is pretty misleading but there is an error in your code, or more accurately your code does not do exactly what the challenge asked you to do.

The challenge asks you to add one item using the append method and then one item using the concatenation technique. You add two items using the concatenation technique, not one. That is what is causing the code checker to complain. The code checker is often pretty picky about having your code do precisely what it asks and not anything more. And this is one of those moments.

If you only add one item like this:

var arrayOfInts: [Int] = [4, 5, 6, 34, 2, 1]
arrayOfInts.append(444)
arrayOfInts += [7]

Then your code will pass the task.

Edit: I see you have already figured out the problem. That's good. But you should keep what I mention above about the code checker being picky in mind for future challenges. This is far from the only task where doing more than what is asked will lead your code to be marked as wrong even if it is actually fine.
