I'm stuck on this challenge. This is my answer to task 4
arrayOfInts.removeAtIndex(5) let discardedValue = arrayOfInts
It says "Make sure you're removing the 6th item from array at index 5! I have done this. Also when I click on preview the area shows blank.
Please give me some help. I'm puzzled!
// Enter your code below
var arrayOfInts = [1, 2, 3, 4, 5, 6]
arrayOfInts.append(7)
arrayOfInts += [8]
let value = arrayOfInts [4]
arrayOfInts.removeAtIndex(5)
let discardedValue = arrayOfInts

you remove an item from the array with the removeAtIndex(_:) method. This method removes the item at the specified index and returns the removed item (although you can ignore the returned value if you do not need it):
removeAtIndex returns the item that was removed. So you can set the value of the constant and remove the item at index 5 in one line
// Enter your code below
var arrayOfInts = [1, 2, 3, 4, 5, 6]
arrayOfInts.append(7)
arrayOfInts += [8]
let value = arrayOfInts [4]
let discardedValue = arrayOfInts.removeAtIndex(5) // the method returns the item that was removed
