iOS Swift Collections and Control Flow Introduction to Collections Working With Arrays

I am very confused on how to assign this to the constant "value" my code in Xcode works... but not on the challenge,

var arrayOfInts = [1,2,3,4,5,6]
arrayOfInts.append(7)
[1,2,3,4,5,6,7] + [8]
arrayOfInts[4]
let firstValue = arrayOfInts[4]
array.swift
// Enter your code below
var arrayOfInts = [1,2,3,4,5,6]
arrayOfInts.append(7)
[1,2,3,4,5,6,7] + [8]
arrayOfInts[4] 
let firstValuealue = arrayOfInts[4]

My Friend, you don't need to repeat the whole array, rather just mention the constant name to which you assigned the array. eg:- " [1,2,3,4,5,6,7] + [8] " this is a wrong way of doing things when you already assigned the list of numbers to constant arrayOfInts then you can simply use that. Xcode doesn't find error because there is nothing wrong in it but practically in the development environment you are just writing the number into an array without the assignment. "arrayOfInts + [8]" this is correct

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

arrayOfInts.append(7)
arrayOfInts += [8]
let value = arrayOfInts[4]
let discardedValue = arrayOfInts.remove(at: 5)

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

arrayOfInts.append(7)

arrayOfInts + [8]
let value = arrayOfInts[4]

let discardValue = arrayOfInts.remove(at: 5)
