Some help please

Where am I going wrong

array.swift 
// Enter your code below
var arrayOfInts = [0,1,2,3,4,5]
arrayOfInts.append(6)
arrayOfInts += [7]
let value = arrayOfInts[4]
let discardedValue = arrayOfInts.removeAtIndex(5)

The issue is that removeAtIndex is not the name of a method. The name of the remove method is simply remove, and the at part is an argument label that is used when passing in the index.

Like this:

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