It keeps saying this code is wrong but I don't really know what I'm doing incorrectly. It worked in Xcode just fine.

// Enter your code below var arrayOfInts: [Int] = [1, 2, 3, 4, 5, 6]

arrayOfInts.append (1)

var concArray: [Int] = [5]

arrayOfInts = arrayOfInts + concArray

let value = arrayOfInts [5]

arrays.swift 
// Enter your code below
var arrayOfInts: [Int] = [1, 2, 3, 4, 5, 6]

arrayOfInts.append (1)

var concArray: [Int] = [5]

arrayOfInts = arrayOfInts + concArray

let value = arrayOfInts [5]

Yeah I figured it out right after I asked the question haha! Since the 5th value of the array would the Int [6] I just went ahead and used [5] to retrieve it... I was thinking about the array items instead of the array indexes haha! Thank you for the help! :)

Hey there ben sasser ! You're doing great! But take a look at that last line. It asks for the fifth value. You're putting the 6th element in the variable value. Remember, unlike humans, most computers start counting at 0. It's going to need this line.

let value = arrayOfInts[4]

Hope this helps! :sparkles:
