Swift Collections and Control Flow Challenge Task help

When I complete Task #1 it says it's fine, but when I complete task 2 is says that Task #1 is no longer passing. I do not have this problem when I put it into playground so I am confused. Did I do anything in task 2 to make task 1 not work??

Here are the instructions: " Since the array is mutable, let's add two more values to the existing array. There are two ways we can add items to an array and I want you to give both a try. First, add one item to the array using the append method.

Remember: We invoke methods on an array using a period or dot. After the dot we write out the method name and a value to append in parentheses following the name.

Next, add another item to the array by concatenating an array. When concatenating, assign the results of the expression back to arrayOfInts."

array.swift
// Enter your code below
var arrayOfInts: [Int] = [1,2,3,4,5,6]
arrayOfInts.append(7)
arrayOfInts = arrayOfInts + [8,9,]

It turns out that you just ONLY needed to add 2 numbers.

// Enter your code below
var arrayOfInts = [1,3,5,7,9,11]
arrayOfInts.append(13)
arrayOfInts = arrayOfInts + [15]

But you were mostly right.
