Task one is getting invalidated. I try in my own Xcode playgrounds and it works.

What am I doing wrong?

// Enter your code below
var arrayOfInts = [1, 2, 3, 4, 5, 6]
arrayOfInts += [9]

Hi Leo,

Looking at the question, the challenge tests will be expecting an array with 8 elements in it after this task. Yours has 9.

If you remove one of you append lines, your code is fine.
