I keep experiencing an odd "Bummer" message in Swift 2.0 Collections and Control Flow.

Question

The problem appears to be in challenge task 2 of 4. On task 1, the code works without issue and takes me to task 2, where if I enter incorrect code, the system will inform me that I made an error. However, when the code appears to be correct and I submit it for checking, I am given the message that task 1 is no longer passing. If I go back, change nothing (or only remove ": [Int]”), then resubmit, I am again granted access to task 2. As a note, I am only experiencing issues through the Team TreeHouse site. Xcode has no issue returning the final array. Am I just not writing this code in the best way or am I misinterpreting the dirtections? Thanks for you help! Colin

arrays.swift

// Enter your code below
var arrayOfInts: [Int] = [1,
    3,
    5,
    7,
    11,
    13]
arrayOfInts.append(17)
arrayOfInts += [19,
    23]

Hey Colin Senfelds,

The challenge wants you to start with a total of 6 items in your array. In task 2 you need to add two more items to the array, using two different methods. The first item you will add with the append() method. The second item you will add by concatenating an array. I completed the code challenge and broke down my code step by step so you can see what the challenge is asking. The reason why your code wasn't passing was possibly because you were adding too many values with your array concatenation or you had more than 6 items in the original array.

// Enter your code below
// Create an array of 6 Ints
var arrayOfInts = [1, 2, 4, 5, 7, 10]

// Add item to array using append() method
arrayOfInts.append(43)

// Add item to the array by concatenating an array
arrayOfInts += [27]

/* Retrieve item 5 from index, and assign result
to a constant named value */

/* Array indexes start at 0 so to access the
5th item we use an index of 4 */
let value = arrayOfInts[4]

/* Remove the 6th item from the array.
We can do this using removeAtIndex()
The removeAtIndex returns the removed value,
so we can assign the value to a variable/constant */

let discardedValue = arrayOfInts.removeAtIndex(5)

Good Luck!
