Make sure you're using the append method to add another to the array. Hint: Append methods are used like this - someArra

why is this wrong

array.swift
// Enter your code below
var arrayOfInts = [0,1,2,3,4,5]

arrayOfInts.append([6])

arrayOfInts += [7]

The append method takes a single number to append, not a number stored in an array. So you should not wrap it in square brackets. It should look like this:

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

arrayOfInts.append(6)

arrayOfInts += [7]
