working with array

Challenge Task 4 of 4

For the last task, remove the 6th item from the array and assign the result to a constant named discardedValue.

To remove an item, use the method remove(at:) and put the index number in between parentheses that you want to remove.

Bummer! Make sure you're assigning the results of the expression to a constant named discardedValue

array.swift

var arrayOfInts = [0,1,2,3,4,5]

arrayOfInts.append(6)

arrayOfInts += [7]

let value = arrayOfInts[4]

let discardedValue.remove (at: 5)

ā€‹

im stuck on the let discardValue please help

array.swift 
var arrayOfInts = [0,1,2,3,4,5]
arrayOfInts.append(6)
arrayOfInts += [7]
let value = arrayOfInts[4]
let  discardedValue.remove (at: 5)

Hi there,

You want to assign the result of the remove(at:) method to a constant named discardedValue. So, you start with 

let discardedValue =

Next, you want to call remove() on arrayOfInts using dot notation. Pass in at: 5 as the parameter. This gives you:

let discardedValue = arrayOfInts.remove(at: 5)

I hope that helps.

Steve.
