"It looks like Task 1 is no longer passing" on simple array challenge.

Task 1 required me to create a new array called arrayOfInts containing 6 numbers.

arrayOfInts = [1,2,3,4,5,6]

Task 2 -

Now that we have an array declared, since it is a mutable array, we can add and remove items. Let's start by adding two more values to our existing array. There are two ways we can add items to an array and I want you to give both a try. 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.

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

This is my complete code.

var arrayOfInts = [1,2,3,4,5,6]

arrayOfInts.append(7)

var secondArray = [8,9,10]

arrayOfInts = arrayOfInts + secondArray

// This is returning an error saying "Task 1 no longer passes" but I cannot see why. Is there an error in my code or is there an error with the challenge itself? This was supposed to be a simple recap, oh deary me :(

I think it says "Task 1 is no longer passing" because you used a second array. I used the += method to append a number to the array. And it only seems to want one number appended at a time, it didn't work when I tried to append multiple numbers.

var arrayOfInts = [8, 4, 5, 2, 6, 9]

arrayOfInts.append(1)

arrayOfInts += [3]

Hope this helps!

Here's your answer. I tried the above code by Malerie but had no luck. Hope this helps anyone else that was struggling!

var arrayOfInts = [23,45,21,17,19,99]
arrayOfInts.append(55)
arrayOfInts += [67]

Why did you use parenthesis for the append line then use brackets while concatenating?

Var arrayOfInts = [1,2,3,4,5,6] arrayOfInts.append ( 44 ) arrayOfInts += [ 7 ] Let value = arrayOfInts [ 4 ] Let discardedValue = arrayOfInts . removeAtIndex
